Safety Tips for Operating an Angle Grinder

Safety Tips for Operating an Angle Grinder有1条评论

Power tools are usually engaged in high-speed motion which can cause danger if precautions are not taken.

Although the chance of injury is minimized using a Hychika angle grinder with a triple safety design( safety switch, auxiliary handle, and wheel guard), there are still a few guidelines to follow in order to stay injury-free all the time.

  1. Disconnect from the power source (the battery pack from the power tool) before making any adjustments, changing accessories, or storing power tools. Inspect parts for misalignment, binding, or breakage.

2. When not in use, store the battery away from other metal objects like paper clips, coins, keys, nails, screws, etc,

3. The outside diameter and the thickness of your discs must be within the capacity rating of your power tool.

4. Threaded accessories must match the grinder spindle thread. Or else the power tool will run out of balance.

5. Wear protective equipment such as a face shield, safety goggles, or safety glasses to stop small abrasive work-piece fragments.

6. Hold the power tool by insulated gripping surfaces only in case the cutting accessory may contact hidden wires.

7. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and lose control.

8. Maintain a firm grip on the power tool to resist kickback forces. Always use an auxiliary handle for maximum control.

9. Never place your hand near the rotating accessory.

10. Do not “jam” the cut-off wheel or apply excessive pressure on it.

11. Do not attempt to make an excessive depth of cut. Over-stressing the wheel increases the chance of wheel twisting or binding.

13. Do not position your body in line with the rotating wheel.

14. When the wheel is binding or the cut interrupted for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop.

15. Do not restart cutting in the workpiece.

16. Be extra careful when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring, etc.

17. Large workpieces tend to sag under their own weight. Supportive pads must be placed under the workpiece near the line of cut.

Be acknowledged of the above, and now you are ready to go!

Cordless

The 20-Volt Cordless 4.5-inch brushed angle grinder by Hychika features an 8500 rpm fast speed thanks to its powerful 18V lithium-ion battery.

The cordless angle grinder is excellent to work with. No need to be tethered to the wall outlet, it is extremely helpful when working both around the house or in professional settings.While it doesn’t boast the highest top speed, the performance remain high standards during tough cuts and grinds. Little vibration is felt thanks to the rubber-over-mold grip. And lock-on switch proved to be a huge plus. Auxiliary handle can be placed in 3 directions allowing cutting and grinding at unusual angles. The compact size and weight of 4.5-inch disc is suffice for DIY projects. When it comes to DIY projects and budgets, you don’t always need to go for top-of-line tools every time. With included discs to rotate over the course of your task, there is no extra shopping and waiting list to tick.

Corded

The corded grinder felt truly in its element on metalworking project, handling cuts and grinds nicely. The use of a dual micro-switch prevents accidental start-up and provides better user protection during use. We also highly recommend the 3-position handle attachment, as it can make cutting much more manageable and suitable for both right-handed and left-handed person. The one negative worth mentioning is that corded models restrict the user to a physical location, limiting range without an extension cord. The cords can also be a tripping hazard.

Niches of Each Type of Cordless Drill/Driver

Niches of Each Type of Cordless Drill/Driver有10条评论

Power drivers and drills, as we can see, bear similar looks (pistol-shaped) and even function similarly to some extent. It seems impossible to tell them apart from one another. They take slightly different forms (mainly the chuck) and occur in their niche more often than others. The next chapters may give you some hints on how to make a choice.

Cordless Screwdriver

Cordless screwdrivers are usually light-weighted and very easy to use. That means they’re ideal for smaller projects around the house, such as assembling a bookshelf, removing a cabinet door, and replacing an outlet cover.

Cordless Drill

Power drills are indispensable tools for home improvement and all types of jobs around the house, small or large. You can equip them with needle-thin bits for drilling tiny holes for craft projects or chuck in large hole saws for cutting up to 5-inch diameter holes in drywall and other soft materials.

Cordless Impact Drivers

Impact drivers excel at driving fasteners into dense or knotty wood. Use Impact Drivers When：

Driving screws into wood or metal (you can use it for drywall if you’ve got a lower speed/torque option)

Driving large diameter screws or lag bolts.

Tightening/loosening bolts, including those that should be very tight or have been stuck.

Unlike drills, impact drivers have quick-release shanks that accept all 1/4 inch hex driver bits.

Cordless Hammer Drill

A hammer drill combines rotational bursts with front-to-back movement (the hammering action) to bore into difficult masonry that presents an obstacle for ordinary drills.

Cordless Impact Wrench

Impact wrenches are found in the tool chests of mechanics everywhere. They’re commonly used for loosening lug nuts from cars and trucks, but they can also be used in any high-torque situation.

How To Decide

If you need to drill holes and drive the occasional medium-sized screw, a regular drill will suit you fine. If you’ve got a deck to build, a plywood sub-floor to install, a treehouse to screw together, or any other job involving lots of wood screws, consider investing in an impact driver.

Everything You Need To Know About The 18V Cordless Tire Inflator By Hychika

留下评论 , ,

When your car’s tire pressure warning light comes on, or if you get a flat tire, a good portable air compressor can top up your tires and help you get back on the road quickly without tire changing and car tugging. Hychika introduces an 18V cordless tire inflator this year targeting such situations.

Application and limitations

It can be used for inflating tires on cars, bikes, sedans, and midsize SUVs, and is also ideal for lifebuoys, sports balls, inflatable boats, and other inflatable items. However, it is not intended for high-pressure RV and commercial truck tires.

High-pressure usage: inflate vehicle tires via a high-pressure hose. This inflator pump can up to a maximum pressure of 160 PSI. For filling car tires, you will only need to run them up to the 32 PSI for most passenger cars, or maybe 35 PSI on a cold day. A portable 1 or 2 CFM compressor, at 90 PSI, should serve you well for filling car tires.

Fig.1

Low-pressure usage: inflate low-pressure large capacity items such as floaters, mattresses via a low-pressure hose. Inflate and deflate both ways.

Fig.2

Dual Power Modes

The cigarette lighter port is a natural AC power outlet. Coupled with our 10 feet long cord, it becomes a strong backup for the battery power.

Fig.3

4Ah battery provides cordless DC charging mode that frees you from wires and plugs. The same 20V Max battery can function in other Hychika tools also.

Fig.4

Smart and Precision Pumping

Preset a pressure value and pump. When reaching the exact pressure needed, the air compressor will stop on itself promptly. And if no operation is detected in 10 minutes, it will shut off automatically.

Expanded Time Slots for Operating

The LCD backlit display can beat the sun or darkness to present you with a clear reading even at night or on bright sunny days.

And the ultra-bright 48Lm (Max 90Lm) LED flashlight is your reliable emergency lighting source for night-time road trips.

Easy Work

The use of a cordless inflator removes the need for strenuous pumping to fill your tires to the right pressure. It can reliably pump up your tires at record speed.

Neat Placing

A sturdy, well-designed housing allows the hoses, power cords, and accessories to all are attached neatly to separate compartments of the unit so they won’t get tangled or misplaced.

What You Get

1 * HYCHIKA 20V Air Compressor, 1 * 2.0A Battery, 1 * 1H Fast Charger, 3 * Nozzle Adapters, 1*Low Pressure Air Hose, 1 * User Manual.

Precautions To Take

Ensure all hose fittings are tight. Loose fittings can decrease performance and cause danger.

Tips for Using a Cordless Mini Chainsaw

Tips for Using a Cordless Mini Chainsaw有11条评论

Limit cutting material to wood only

Never use a mini chainsaw for cutting any non-wood material, including plastic, masonry, or metal. Never cut a tree or branch with a diameter wider than the length of the mini chainsaw’s guide bar. 

Tension the Chain Properly

Make sure that the chain is properly tensioned on the guide bar. A loose chain may whip free or draw materials into it. A tight chain may not move at all or have a higher risk of breaking down during heavy-duty operations.

A thumb of rule: pull the chain to check the tightness of fitting. Let the upper side of the down chain bite loosely with the guide bar but leave no clearance when you pull the down chain with force.

Avoid kickback

Kickback results from the tip of the moving chainsaw being allowed to come into contact awkwardly with an object. The tip may bounce wildly backward and injure the worker.

The guide bar of the mini chainsaw should be 1-2 inches longer than the diameter of what you need to cut. Chainsaws with a top flap or low kickback have a lower risk of kickback incurred injury.

Sharpen the chain regularly

There’s no hard-and-fast rule on how often you need to sharpen your chainsaw, but many experts recommend doing it every time you need to refuel the tool.

Follow the dressing code

Do not wear loose-fitting clothing, dangling jewelry, or anything else that could become caught in the chain of the saw.

Avoid Touching the Chain, Even When Stationary

Chainsaws’ chains are very sharp. Even when the chain is not moving, it can severely lacerate the skin. Be sure to keep the cover on the saw when not in use or remove the battery so the machine doesn’t start at all.

Lubricate the chain in a timely manner

The oil lubricates the bar and chain, preventing premature wear and possible derailing of the chain. 

After the oil is applied, run the chainsaw for a few seconds until it is spread evenly onto the chain. While manual oiling may be a little tricky to handle, there are auto oiling options that distribute a consistent, steady flow of oil onto the chain. Check the oil tank to keep track of the oil level for a timely refill.

Looking into Hychika 18V Cordless Mini Chainsaw for Home Reno and Garden Caring有2条评论

As the cordless chainsaw is applauded for its efficiency in felling large trees and lumberjacking, homeowners and gardeners are seeking its downsized version to attend to their backyards and DIY home makeover projects, even wood carving. Thus the birth of mini chainsaw.

Hychika digs a little deeper into people’s true needs and concerns and takes action. Hychika’s newly launched mini chainsaw attains some lacking features on the market, doubles the safety settings, boosts cutting efficiency.

Brushless motor

Brushless motors eliminate the friction that exists in brushed ones and are less likely to be eroded in use. That means 10 times’  the life of the brushed counterparts. Plus, the brushless motor is more energy-efficient, works longer between charges.

With less vibration, the rattle on this single-hand operated chainsaw is lower than its counterparts; that means less fatigue during the job.

Trimming, logging, cutting in one

Chainsaws are hugely helpful tools for clearing brush, cutting firewood, felling trees, and removing branches.

While a mini chainsaw isn’t the tool to fell a mighty oak tree, its 8-inch blade makes quick work of pruning tree limbs, saplings, and brushes.

Hychika filled the opening of 8-inch cutting diameter in the market and can fulfill a wider range of cutting purposes.

As the new year holiday is drawing near, you might want to pick up speed in clearing up your backyards or home renovation to welcome the long-parted guests. A mini chainsaw like this is a good helper.

Safety lock, top and bottom baffle

The built-in safety lock-off button and the trigger start the machine only when pressed down simultaneously. It is a double security setting for a cordless mini chainsaw.

The top buffer not only prevents sawdust flying but also minimizes human injury in cases of kickback or accidentally touching the saw blade.

Additionally, Hychika 18V mini chainsaw installs a bottom baffle to cushion users from potential injury at the finishing stroke of cutting.

Cutting lumber like butter

If you have ever cut trees by hand, you will be surprised at a chainsaw’s speed. 2.5-inch lumber is cut in 5 seconds. And manpower is significantly saved in larger lumberjacking projects.

Industry lowest and balanced weight

The bare machine is only 3.1 pounds. It is a balanced weight that works well also for female users.

Auto oiler lubrication

Our chainsaw has a fixed-flow oiler that distributes a consistent, steady flow of oil onto the chain. No tedious and messy steps of manual lubrication.

If you fail to lubricate the chains, the blade may become dull more quickly, and the friction heat can also cause the nose of the saw to warp.

The embedded oil tank of the mini chainsaw is a 30 ml translucent white cell that allows you to keep track of the oil level and refill the tank timely. Our kit includes a bottle of 100 ml oil refill for you to kick off your first chainsaw cutting journey without further shopping and waiting.

Cordless and portable

The battery-powered chainsaw allows you to grab the portable cordless chainsaw and instantly start trimming around the backyard.

The battery can handle roughly 100 cuts on a single charge(the specific value varies with the actual size and hardness of the wood), and the lithium battery recharges reasonably quickly.

Ease of use

The step-by-step guided installation of a mini chainsaw is as fun as playing Lego.

Rubberized and ergonomic grip eliminates fingers and wrist strains. Further, the single-hand operation allows cutting nimbly and makes cutting easy in tightly confined spaces.
