General Tool Handling Guidelines:
1. Always assume that the tool contains fasteners.
2. Do not point the tooltowardyourself or anyonewhether it contains fastenersor not.
3. Do not actuate the tool unless the tool is placed firmly against the workpiece.
4. Respect the tool as a working implement.
5. No horseplay.
6. Do not hold or carry the tool with a finger on the trigger.
7. Do not loadthetool with fasteners whenany one of the operatingcontrols isactivated.
8. Do not operate the tool with any power source other than that specified in the tool
An improperlyfunctioning tool mustnot beused.
operatingkafety instructions.
.Sparks sometimesfly when the tool
is used. Do
not usethetool nearvolatile, flammable materials
suchas gasoline, thinner, paint, gas, adhesives,
etc.; they will igniteandexplode, causingserious
injury.
The area should be sufficiently illuminated to
assure safe operations.
The area should be clear and litter- free. Be
especially careful to maintain good footing and
balance.

Onlythoseinvolved in thework should be in the
vicinity. Childrenespecially mustbekept away at
all times.
There may belocalregulations concerningnoise
which must be compliedwith by keeping noise
levelswithin prescribed limits. Incertain cases,
shutters should be used to contain noise.
.Securing the trigger in the ON position is also
very dangerous. Never attempt to fasten the
trigger.
Do not operate a tool if any portion of the tool
operating controls is inoperable, disconnected,
altered, or not working properly.
Operatethetoolwithinthe specified air pressure
of
4.5 - 8.5 kgf/cmzG (65 - 120 PSIG) for safety
and longer tool life.
Do not exceed the recom-
mended max. operating pressure of
8.5
kgf/cmzG (120 PSIG). The tool should not be
connectedto asourcewhose pressure potentially
exceeds
14.0 kgf/cm'G (200 PSIG).

.Never use the tool with other than compressed
air. If bottledgas (carbon dioxide, oxgen, nitro-
gen, hydrogen, air, etc.) or combustible gas
(hydrogen, propane, acetylene, etc.) is used as
apowersourcefor thistool, thetoolwillexplode
and cause serious injury.
.Always check the tool for its overall condition
and loose screws before operation. Tighten as
required.
Make sure the safety system is in working order
before operation. The tool must not operate if
only the nail guide ispressedagainst the wood.
Test for possible faulty operation with nails un-
loaded and the adjuster set to the number
1.
Checkwalls, ceilings, floors, roofingandthe like
carefully to avoid possible electrical shock, gas
leakage, explosions, etc. caused by strikinglive
wires, conduits or gas pipes.

Makesure noone isnearby before nailing. Never
attempt to nail from boththe inside and outside
at the same time. Nails may rip through and/or
fly
off, presenting a grave danger.
.Watch your footing and maintain your balance
with the tool. Make sure there is no one below
when working inhigh locations, and secure the
air hose to prevent danger if there is sudden
jerking or catching.

Perform cleaning and maintenance right after
finishing the job. Keepthe tool
in tip-top condi-
tion. Lubricate moving parts to prevent rusting
and minimize friction related wear. Wipe
off all
dust from the parts.
.Do not operate this tool if it does not contain a
legible WARNING LABEL.
Do not modify tool without authorization from
Makita.
Ask Makita's Factoryor Authorizedservicecenter
for periodical inspection of the tool.

TOOL INSTALLATION INSTRUCTIONS AND USE
Selecting compressor
The air compressor must comply with the requirements of
Selecta compressorthat hasample pressureandair output
to assure cost-efficient operation. The graph shows the
relation between nailing frequency and compressor air
output at a compression of 8.5 kgf/cm2G(120 PSIG). Thus,
for example, when you drive about 10 nails 3.75 mm x 90
mm (0.148” x 3-1/2”) per minute, a compressor with an air
output over 55 Uminute is required. Pressure regulators
must be used to limit air pressure to the rated pressure of
the tool where air supply pressureexceedsthe tool’s rated
pressure. Failureto do so may resultinserious injuryto tool
operator or persons in the vicinity.
NOTE: Nail size indicates diameter x length.
ANSI 819.3 - 1981.
Selecting air hose
Usean air hoseas largeandas short as possibleto assure
continuous,efficient nailing operation.With an air pressure
of 5 kgf/cm2G (70 PSIG), an air hose with an internal
diameter of over 8.5 mm (5/16”) and a length of less than
20 m (6.6 ft.) is recommended when the interval between
each nailing is 0.5 seconds. Air supply hoses shall have a
minimum working pressure rating of 10.7 kgf/cm2G(150
PSIG)or 150 percent of the maximum pressure produced
in the system whichever is higher.

Lubrication
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possible to the tool. Adjust
the oiler so that one drop of oil will be provided for every
20 nails.
When an air set is not used, oil the tool with pneumatictool
oil by placing 2 (two) or 3 (three) drops into the air fitting.
This should bedone beforeand after use. For proper lubri-
cation, the tool must befired a couple of times after pneu-
matic tool oil is introduced.
