Screwdriver Safety Warnings; Functional Description - Makita 6842 Instruction Manual

Screwdriver safety warnings

1. Hold the power tool by insulated gripping
surfaces, when performing an operation where
the fastener may contact hidden wiring or its
own cord. Fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
Always be sure you have a firm footing.
2.
Be sure no one is below when using the tool in
high locations.
Hold the tool firmly.
3.
4. Keep hands away from rotating parts.
5. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely
hot and could burn your skin.
6. Always secure workpiece in a vise or similar
hold-down device.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product.
MISUSE or failure to follow the safety rules stated
in this instruction manual may cause serious
personal injury.

This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
CAUTION:
• Always check the direction of rotation before
operation.
• Use the reversing switch only after the tool
comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may dam-
age the tool.
Hook
The hook is convenient for hooking the tool to your belt.
It can be installed on either side of the tool.
Changing the installation position of hook allows two-
way setting of 10 mm and 20 mm distance from the tool
itself.
The tool with hook can be hung on the waist belt, a
maximum diameter 20 mm pipe etc.
To remove the hook, just remove the clamping screw.
