Assembly and Operation

Handle

Screw the handle into the screw hole of the handle base and tighten it. Turn the handle to check whether the

guide plate moves freely.

Pre-Operation Check

When the power is turned on, the standby indicator lights up green. Press the magnet switch, and the light on

the suction cup indicates that the magnetic holder is in working condition. Use an iron bar or block to check

whether there is suction at the bottom of the magnetic holder. A strong suction indicates that the magnetic holder

is functioning normally and can be used. When the suction cup switch is pressed again, the indicator light of the

magnetic base will be off, and the magnetic base will lose its magnetic function.

IMPORTANT! Excessively rough and uneven adsorption on the surface will have a certain impact

on the adsorption force of the magnetic drill, so you must first test to prevent accidents.

Operating the Machine

Plug in the power plug, align the drill bit to the position you need, then turn on the electromagnet switch, use the

magnet to attach to the surface of magnetic materials such as steel, ensure the surface is free of debris and

check whether the magnetic force is normal by pushing it side to side. (Generally, the thickness of the steel plate

should be greater than 15mm).

The motor switch can only be turned on when the suction cup is switched ON.

In any case, the tool should only be started in a no-load state. NEVER start the tool with load.

•

The magnetic drill should be checked and maintained frequently. Check whether the power cord, internal

wiring, plug, and switch are in good working condition, whether the insulation resistance is normal, and

whether the transmission parts are damaged.

•

The transmission parts (i.e., gears, racks) in the magnetic drill should always be lubricated and kept clean.

•

When disassembling and inspecting the magnetic base drill, every part should be kept, including the

insulating gasket sleeves, etc. If damaged, the same parts must be replaced with new ones, and all parts

should be installed in the original position during assembly, and no omissions should be made.

Replacement Brush

•

When the tool has large sparks during operation or stops running, replace the brush.

•

Use a screwdriver to unscrew the brush cover, move the spring on the brush, take out the worn brush and

install a new brush, and confirm that the brush slides freely into the hole, and then tighten the brush holder.

•

Be sure to replace both brushes at the same time and use original brushes from the supplier.
