SAFETY WARNING AND INSTRUCTIONS.
KEEP THESE INSTRUCTIONS WITH THE TOOL FOR FUTURE
REFERENCE.
1. SAFETY INSTRUCTIONS
TO AVOID SEVERE PERSONAL INJURY OR
PROPERTY DAMAGE
BEFORE USING THE TOOL, READ
CAREFULLY AND UNDERSTAND THE
FOLLOWING “SAFETY INSTRUCTIONS”.
FAILURE TO FOLLOW WARNINGS COULD
RESULT IN DEATH OR SERIOUS INJURY.
1. WEAR SAFETY GLASSES OR GOGGLES
Danger to the eyes always exists due to the
possibility of dust being blown up by the
exhausted air or of a fastener flying up due to
the improper handling of the tool. For these
reasons, safety glasses or goggles shall
always be worn when operating the tool.
The employer and/or user must ensure that
proper eye protection is worn. Eye protection
equipment must conform to the requirements
of the American National Standards Institute,
ANSI Z87.1 (Council Directive 89/686/EEC of
21 DEC. 1989) and provide both frontal and
side protection.
The employer is responsible to enforce the
use of eye protection equipment by the tool
operator and all other personnel in the work
area.
NOTE: Non-side shielded spectacles and
face shields alone do not provide adequate
protection.

2. EAR PROTECTION MAY BE REQUIRED IN
SOME ENVIRONMENTS
As the working condition may include
exposure to high noise levels which can lead
to hearing damage, the employer and user
should ensure that any necessary hearing
protection is provided and used by the
operator and others in the work area.
3. DO NOT USE ANY POWER SOURCE
EXCEPT AN AIR COMPRESSOR
The tool is designed to operate on
compressed air. Do not operate the tool on
any other highpressure gas, combustible
gases (e.g., oxygen, acetylene, etc.) since
there is the danger of an explosion. For this
reason, absolutely do not use anything other
than an air compressor to operate the tool.
4. OPERATE WITHIN THE PROPER AIR
PRESSURE RANGE
The tool is designed to operate within an air
pressure range of 70 to 100 p.s.i. (5 to 7 bar).
The pressure should be adjusted to the type
of the work being fastened. The tool shall
never be operated when the operating
pressure exceeds 120 p.s.i. (8 bar).
Never connect the tool to air pressure which
potentially exceeds 200 p.s.i. (14 bar) as the
tool can burst.
5. DO NOT OPERATE THE TOOL NEAR A
FLAMMABLE SUBSTANCE
Never operate the tool near a flammable
substance (e.g., thinner, gasoline, etc.).
Volatile fumes from these substances could
be drawn into the compressor and
compressed together with the air and this
could result in an explosion.
6. DO NOT USE A WRONG FITTINGS
The connector on the tool must not hold
pressure when air supply is disconnected. If a
wrong fitting is used, the tool can remain
charged with air after disconnecting and thus
will be able to drive a fastener even after the
air line is disconnected, possibly causing
injury.
7. DISCONNECT THE AIR SUPPLY AND
EMPTY THE MAGAZINE WHEN THE TOOL
IS NOT IN USE
Always disconnect the air supply from the tool
and empty the magazine when operation has
been completed or suspended, when
unattended, moving to a different work area,
adjusting, disassembling, or repairing the tool,
and when clearing a jammed fastener.

fasteners will cause the tool malfunction. Be
sure to use only specified fasteners when
operating the tool.
12. PLACE THE DISCHARGE OUTLET ON THE
WORK SURFACE PROPERLY
Failure to place the discharge outlet of the
nose in a proper manner can result in a
fastener flying up and is extremely
dangerous.
13. KEEP HANDS AND BODY AWAY FROM
THE DISCHARGE OUTLET
When loading and using the tool, never place
a hand or any part of body in fastener
discharge area of the tool. It is very
dangerous to hit the hands or body by
mistake.
14. DO NOT DRIVE FASTENERS CLOSE TO
THE EDGE AND CORNER OF THE WORK
AND THIN MATE RIAL
The workpiece is likely to split and the
fastener could fly free and hit someone.
8. INSPECT SCREW TIGHTNESS
Loose or improperly installed screws or bolts
cause accidents and tool damage when the
tool is put into operation. Inspect to confirm
that all screws and bolts are tight and
properly installed prior to operating the tool.
9. DO NOT TOUCH THE TRIGGER UNLESS
YOU INTEND TO DRIVE A FASTENER
Whenever the air supply is connected to the
tool, never touch the trigger unless you intend
to drive a fastener into the work. It is
dangerous to walk around carrying the tool
with the trigger pulled, and this and similar
actions should be avoided.
10. NEVER POINT THE DISCHARGE OUTLET
TOWARD YOURSELF AND OTHER
PERSONNEL
If the discharge outlet is pointed toward
people, serious accidents may be caused
when misfiring. Be sure the discharge outlet
is not pointed toward people when connecting
and disconnecting the hose, loading and
unloading the fasteners or similar operations.

MODEL IDENTIFICATION
CONTACT TRIP
The common operating procedure on “Contact
Trip” tools is for the operator to contact the work
to actuate the trip mechanism while keeping the
trigger pulled, thus driving a fastener each time
the work is contacted. This will allow rapid
fastener placement on many jobs, such as
sheathing, decking and pallet assembly.
All pneumatic tools are subject to recoil when
driving fasteners. The tool may bounce, releasing
the trip, and if unintentionally allowed to recontact
the work surface with the trigger still actuated
(finger still holding trigger pulled) an unwanted
second fastener will be driven.
CONTACT TRIP
Identified by BLACK TRIGGER.
SEQUENTIAL TRIP
The Sequential Trip requires the operator to hold
the tool against the work before pulling the trigger.
This makes accurate fastener placement easier,
for instance on framing, toe nailing and crating
applications. The Sequential Trip allows exact
fastener location without the possibility of driving
a second fastener on recoil, as described under
“Contact Trip”.
The Sequential Trip Tool has a positive safety
advantage because it will not accidentally drive a
fastener if the tool is contacted against the workor anything else-while the operator is holding the
trigger pulled.
SEQUENTIAL TRIP

5. MAINTAIN FOR
PERFORMANCE
q
DO NOT FIRE THE STAPLER WHEN IT IS
EMPTY
w
USE A 3-PIECE AIRSET
Failure to use a 3-piece airset allows the
moisture and dirt inside compressor to pass
into the tool directly. This causes rust and
wear, and results in a poor operating
performance. The hose length between airset
and tool should be no longer than 5 m since a
longer length results in a reduction in air
pressure.
e
USE RECOMMENDED OIL
The velocite or turbine oil should be used to
lubricate the tool. Upon completion of
operations, place 2 or 3 drops of oil into the air
plug inlet with the jet oiler. (Recommended Oil
: ISO VG32)
r
INSPECT AND MAINTAIN DAILY OR
BEFORE OPERATION
Disconnect air supply and empty the
magazine when inspecting or maintaining the
tool.
(1) Drain air line filter and compressor
(2) Keep lubricator filled in air 3-pieces set
(3) Clean filter element of air 3-pieces set
(4) Tighten all screws
(5) Keep contact arm moving smoothly
6. STORING
q
When not in use for an extended period, apply
a thin coat of the lubricant to the steel parts to
avoid rust.
w
Do not store the tool in a cold weather
environment. Keep the tool in a warm area.
e
When not in use, the tool should be stored in a
warm and dry place. Keep out of reach of
children.
r
All quality tools will eventually require servicing
or replacement of parts because of wear from
the normal use.
7. TROUBLE
SHOOTING/REPAIRS
The troubleshooting and/or repairs shall be
carried out only by the MAX CO., LTD. authorised
distributors or by other specialists.
Supplement to the operating instruction
According to the European Norm EN 792-13 the
regulation is valid from 01.01.2001 that all
fastener driving tools with contact actuation must
be marked with the symbol “Do not use on
scaffoldings, ladders” and they shall not be used
for specific application for example:
＊when changing one driving location to another
involves the use of scaffoldings, stairs, ladders
or ladder alike constructions e.g. roof laths,
＊closing boxes or crates,
＊fitting transportation safety systems e.g. on
vehicles and wagons.
