mechanism may be under compression and the fastener
may be forcefully discharged while attempting to free a
jammed condition.
• Do not use this nailer for fastening electrical cables. It is
not designed for electric cable installation and may damage
the insulation of electric cables thereby causing electric shock
or fire hazards.
• Always wear safety glasses.
• Always wear ear protection.
• Only use fasteners of th e type specified in the manual.
• Do not use any stands for mounting the tool to a support.
• Do not disassemble or block any parts of the fastener driving
tool such as the contact trip.
• Prior to each operation check that the safety
and triggering mechanism is functioning properly and that all
nuts and bolts are tight.
• Do not use the tool as a hammer.

ʵ when changing from one driving location to another
involving the use of scaffoldings, stairs, ladders or
ladder‑like constructions, e.g., roof laths, etc.;
ʵ when closing boxes or crates;

• Never point any operational fastener driving tool at yourself or
at any other person.
• While working, hold the tool in such a way that no injuries can
be caused to the head or to the body in the event of a possible
recoil due to a disruption in the energy supply or hard areas
within the work piece.
• Never actuate the fastener driving tool into free space.
• In the work area, carry the tool at the workplace using only
one handle, and never with the trigger actuated.

tool damage perform tool operation check as defined in
the Mode selection section of the manual. If it doesn't
perform according to the manual, stop using the tool and
have it serviced at an authorised D
• Hold tool by insulated gripping surfaces when
performing an operation where driven fastners may
contact hidden wiring. Contact with a "live" wire will make
exposed metal parts of the tool "live" and shock the operator.
Always wear appropriate personal hearing and other
•
protection during use. Under some conditions and duration
of use, noise from this product may contribute to hearing loss.
• Disconnect battery pack from the tool when not in use. Always
remove battery pack and remove fasteners from magazine
before leaving the area or passing the tool to another
operator. Do not carry tool to another work area in which
changing location involves the use of scaffoldings, stairs,
ladders, and the like, with battery pack connected. Do not
make adjustments, perform maintenance or clear jammed
fasteners while battery is in place.
• Do not remove, tamper with, or otherwise cause the
tool, trigger, trigger lock‑off, or contact trip to become
inoperable. Do not tape or tie trigger or contact trip in the
on position. Do not remove spring from contact trip. Make
daily inspections for free movement of trigger and contact trip.
Uncontrolled discharge could result.
• Inspect tool before use. Do not operate a tool if any
portion of the tool, trigger, trigger lock‑off, or contact
trip is inoperable, disconnected, altered, or not working
properly. Damaged parts or missing parts should be repaired
or replaced before use. Refer to Maintenance.
• Do not alter or modify the tool in any way.
• Always assume that the tool contains fasteners.
• Do not point the tool at co‑workers or yourself at
any time. No horseplay! Work safe! Respect the tool as a
working implement.
• Do not carry the tool from place to place holding the
trigger. Accidental discharge could result.
• Always use trigger lock‑off when tool is not in
immediate use. Using the trigger lock‑off will prevent
accidental discharge.
• Do not overreach. Maintain proper footing and balance at all
times. Loss of balance may cause personal injury.
• Use the tool only for its intended use. Do not discharge
fasteners into open air, concrete, stone, extremely hard
woods, knots or any material too hard for the fastener
to penetrate. Do not use the body of the tool or top
cap as a hammer. Discharged fasteners may follow an
unexpected path and cause injury.
• Always keep fingers clear of contact trip to prevent
injury from inadvertent release of the pusher.
• Always operate the tool in a clean, lighted area. Be sure
the work surface is clear of any debris and be careful not to
WALT service centre.
