Read all instructions before using this
tool!
1. Keep work area clean. Cluttered
areas invite injuries.

Do not use electrically powered tools
in the presence of ammable gases or
liquids.

extension cords.
7. Use eye and ear protection. Always
wear ANSI approved impact safety
goggles and ear protection. Wear a
full face shield if you are producing
metal lings or wood chips. Wear an
ANSI approved dust mask or respirator
when working around metal, wood, and
chemical dusts and mists.
8. Do not overreach. Keep proper
footing and balance at all times. Do
not reach over or across running
machines.

sharp and clean for better and safer
performance. Follow instructions for
lubricating and changing accessories.

11. Remove adjusting keys and
wrenches. Check that keys and
adjusting wrenches are removed
from the tool or machine work surface
before plugging it in.
12. Avoid unintentional starting. Do not
carry any tool with your nger on the
trigger, whether it is plugged in or not.
13. Stay alert. Watch what you are doing,
use common sense. Do not operate
any tool when you are tired.
14. Take caution as some woods
contain preservatives such as
copper chromium arsenate (CCA)
which can be toxic. When drilling
these materials extra care should be
taken to avoid inhalation and minimize
skin contact.
15. WARNING: Some dust created by
power sanding, sawing, grinding,
drilling, and other construction
activities, contains chemicals
known [to the State of California] to
cause cancer, birth defects or other
reproductive harm. Some examples
of these chemicals are:
Lead from lead-based paints
Crystalline silica from bricks and
cement or other masonry products
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures
varies, depending on how often you
do this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with
approved safety equipment, such as
those dust masks that are specially
designed to lter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
16. People with pacemakers should
consult their physician(s) before
use. Electromagnetic elds in close
proximity to heart pacemaker could
cause pacemaker interference or
pacemaker failure. In addition, people
with pacemakers should:
• Avoid operating alone.
• Don’t use with power switch locked
on.
• Properly maintain and inspect to
avoid electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit
Interrupter (GFCI) should also be
implemented – it prevents sustained
electrical shock.
17. Check for damaged parts. Before
using any tool, any part that appears
damaged should be carefully checked
to determine that it will operate
properly and perform its intended
function. Check for alignment and
binding of moving parts; any broken

should be properly repaired or replaced
by a qualied technician. Do not use
the tool if the trigger does not turn On
and Off properly.

Prevent body contact with grounded
surfaces such as pipes, radiators,
ranges, and refrigerator enclosures.
