• 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
lose footing when working in elevated environments such
as rooftops.
• Do not drive fasteners near edge of material. The
workpiece may split causing the fastener to ricochet, injuring
you or a co-worker. Be aware that the nail may follow the
grain of the wood (shiner), causing it to protrude unexpectedly
from the side of the work material. Drive the chisel point of the
nail perpendicular to the grain to reduce risk of injury.
• Do not drive nails onto the heads of other fasteners or with the
tool at too steep an angle. Personal injury from strong recoil,
jammed fasteners, or ricocheted nails may result.
Keep hands and body parts clear of immediate work
•
area. Hold workpiece with clamps when necessary to keep
hands and body out of potential harm. Be sure the workpiece
is properly secured before pressing the nailer against the
material. The contact trip may cause the work material to
shift unexpectedly.
• Do not use tool in the presence of flammable dust, gases
or fumes. The tool may produce a spark that could ignite
gases causing a fire. Driving a nail into another nail may also
cause a spark.
• Keep face and body parts away from back of the tool
cap when working in restricted areas. Sudden recoil can
result in impact to the body, especially when nailing into hard
or dense material.
• Grip tool firmly to maintain control while allowing tool to
recoil away from work surface as fastener is driven. In Bump
32
mode if contact trip is allowed to recontact work surface
before trigger is released an unwanted fastener will be driven.
• Choice of triggering method is important. Check the manual
for triggering options.
Sequential/Bump Selector Switch
Sequential Action
When using the tool in sequential mode, do not
•
actuate the tool unless the tool is placed firmly against
the workpiece.
Bump Action (Fig. D)
• When using the tool in bump action, be careful of
unin tentional double fires resulting from tool recoil.
Unwanted fasteners may be driven if the contact trip is
allowed to accidentally re-contact the work surface.
• When "bump" actuating the finish nailer, always keep
tool in control. Inaccurate placement of tool can result in
misdirected discharge of a fastener.
To Avoid Double Fires:
•
- Do not engage the tool against the work surface with a
strong force.
- Allow the tool to recoil fully after each actuation.
- Use tool in sequential mode.
Do not drive nails onto the heads of other fasteners.
•
Strong recoil, jammed fasteners, or ricocheted nails may result.
Be aware of material thickness when using nailer. A
•
protruding nail may cause injury.
Depth adjustment: To reduce risk of serious injury from
•
accidental actuation when attempting to adjust depth,
ALWAYS;
- Remove battery pack.
-
Engage trigger lock.
- Avoid contact with trigger during adjustments
• Do not drive nails blindly into walls, floors or other work
areas. Fasteners driven into live electrical wires, plumbing, or
other types of obstructions can result in injury.
• Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power
tools may result in serious personal injury.
Residual Risks
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment of hearing.
• Risk of personal injury due to flying particles.
• Risk of burns due to accessories becoming hot
during operation.
• Risk of personal injury due to prolonged use.
Electrical Safety
The electric motor has been designed for one voltage only.
Always check that the battery pack voltage corresponds to the
