OPERATING TIPS AND MAINTENANCE
Operating Guides and Tips
Avoid overloading
heads. Do not apply excessive pres-
sure to the tool while using. If the
speed drops abnormally, decrease
pressure immediately. When drilling,
if the bit stops abruptly or becomes
blocked, release the trigger at once.
Reverse the direction to free the drill
bit.
Ensure the safety of the workplace.
Clear the work area of all parts and
debris that may cause injury by flying
objects. Securely fix the object to be
worked on in a vise or otherwise
clamp to avoid injury. Do not attempt
to hold workpiece by hand.
Inspect the cordless tool before use.
Run the tool before using to ensure
all parts are running smoothly and
there are no abnormal sounds or
sparks. If any defect is found, have
unit serviced.
Know your work site. Take care to make
sure the material being worked on is
not supporting another structure, or
that there are no obstructions.
Before drilling or sawing. check
behind walls for wires, other electri-
cal hazards, or plumbing.
Use accessories properly. Use the low-
est possible torque setting when dri-
ving fasteners. This will increase the
life span of the driving bit and pre-
vent damage to the fastener.
