PRIMING
CHANGING MANDRELS
STROKE ADJUSTMENT
PRIMING PROCEDURE
Priming is ALWAYS necessary after the tool has been dismantled and prior to operating. It may also be
necessary to restore the full stroke after considerable use, when the stroke may be reduced and fasteners
are not fully placed by one operation of the trigger.
OIL DETAILS
The recommended oil for priming is mineral oil based hydraulic oil like Castrol Hyspin VG 32 or other.
• Place tool on its side, oil plug 42 side up.
• Pull back stroke set finger 88 and unscrew rear casing 86 by a maximum of 5 turns from the fully 'IN' position.
• With an Allen key, unscrew oil plug 42 and remove with oil seal washer 43.
• Fill tool with priming oil rocking gently to expel air.
• Replace oil seal washer 43 and oil plug 42 and tighten.
• You must now bleed screw 48 is fully tightened unscrew by ONE TURN only, using an Allen key.
Connect the tool to the air supply and depress the trigger.
• Wait until oil appears all around oil bleed screw 48 then re-tighten. Wipe excess oil away.
• Release the trigger.
• Using an Allen Key open oil plug 42.
• Top-up with priming oil to reset level. Replace oil seal washer 43 and oil plug 42 and fully tighten.
• It is necessary to fit the appropriate nose equipment and adjust the tool stroke prior to operating the tool.
Item numbers in bold refer to general assembly drawings and parts list. (Pages 5-6).
Release lock and rotate rear drum to adjust applied stroke to the rivet nut, up to 7mm.
To change mandrel, remove this nose
cover then push back the roll pin in the
window by hand.
This releases the hex drive into the
mandrel for easy unthreading.

WARNING
MAINTENANCE INSTRUCTION
1.) LUBRICATION:
Before connection of the hose, apply 4 to 5 drops
of a good quality air tool oil at the air inlet.
After 3 to 4 hours of operation, oiling may be
necessary again.
2.) TIGHTNESS OF PARTS:
Regularly check whether all connecting parts are
fastened securely. Follow this procedure daily
before beginning work.
3.) STORAGE:
Avoid storing the tool in a location subject to high
humidity. If the tool is left unused, the residual
moisture inside the tool can cause rust. Before
storing and after operation, oil the tool at the air
inlet with a good quality air tool oil and run it for
a short period.
4.) DISPOSAL:
Follow national legislation of waste disposal.
5.) ORDERING SERVICE PART:
For further operational and handling information
or for replacement of parts and components,
contact the sales agent from where you purchased
the tool, or the service division of our company,
phone number 800-221-9705.
* When ordering parts and components, give each
part number, name, and quantities.
Users of this tool should review the chemical
composition of the work surface and any products
used in conjunction with this tool for any such
chemicals prior to engaging in any activity that creates
dust and/or microscopic particles.
Users should obtain the Material Safety Data
Sheets for all identified chemicals, either from the
manufacturer or their employer, and proceed to study,
understand, and follow all instructions and warnings
for exposure to such chemicals.
Some examples of these chemicals are: lead from
lead based paints; crystalline silica from bricks,
cement and other masonry products; and arsenic and
chromium from chemically treated lumber. A listing of
the chemicals can be obtained at
www.oehha.ca.gov under Propoisition 65.
In order to reduce their exposure to such chemicals,
users should always:
- work in well-ventilated areas.
- wear appropriate safety equipment and clothes that
are specifically designed to filter out microscopic
particles.
1. The tool shall not be used in potentially explosive
atmospheres.
2. Disconnect the air hose before changing or adjusting
any inserted tools.
3. Before using tool, please confirm all couplings and
plugs are fixed securely. An air hose that is under
pressure may lash out when disconnected and could
lead to serious injuries.
4. Prevent loose clothes, long hair or any other personal
accessories from coming close to moving parts to
reduce the risk of being caught, trapped or drawn into
the rotating spindle.
5. Excessive high air pressure that exceeds the maxi-
mum pressure may cause injuries to user.
6. Exposure to strong vibration for extended time may
cause harm to operator.
7. Be aware of the rotation direction before starting the
tool to reduce hazardous situations due to unexpected
rotation direction.
8. WATCH YOUR STEP! Leaving excess hose unattend-
ed near working area or walk path could result in
injury or death.
9. Wearing eye/face protection could reduce the danger
to person from high speed splinters being emitted
from the tool or work surface.
10. Wearing correct breathing protection will help avoid
inhaling dust or debris from work process that can be
harmful to your health.
11. High sound levels can cause permanent hearing loss.
Use hearing protection while operating tool.
12. Due to the material being processed, there may be a
risk of explosion or fire. Be aware of work surface
dangers prior to beginning work.
13. There is a risk of being cut due to high speed rotation.
Do not touch high speed rotating disc.
14. This power tool is not insulated. If contact is made with
an electric current, injury may occur.
15. Dust created by sanding, sawing, grinding, drilling and
other related activities may expose the user to dust
and/or microscopic particles that may contain chemi-
cals known to the State of California to cause cancer,
birth defects or other reproductive harm.

The oil and water extractor should not be mounted on
or near the air compressor.
The temperature of air is greatly increased during
compression. As the air cools down to room
temperature, in the air line, on its way to the Air Power
Tool, the moisture contained in it condenses. Thus, for
maximum effectiveness, the oil and water extractor
should be mounted at some point
in the air supply system where the temperature of the
compressed air in the line is likely to be lowest. Air
lines must be properly drained daily. Each low point in
an air line acts as a water trap. Such points should be
fitted with an easily accessible drain. See diagram
below. Pitch all air lines back towards the compressor
so that condensed moisture will flow back into the air
receiver where it can be drained off.
Drain daily.
