GENERAL SAFETY
1. Read the manual and understand all safety
instructions before operating the tool. If you have
questions, contact Uline at 1-800-295-5510.
2. Never use flammable gases as a power source for
the stapler. Only use filtered, compressed air.
3. Never use gasoline or other flammable liquids to
clean the stapler. Vapors left on the stapler could
ignite and cause the tool to explode.
4. Do not exceed 110psi of air pressure when
operating the stapler.
5. Disconnect the stapler from the air supply before
making adjustments, cleaning or clearing jams and
when not in use.
6. Do not pull the trigger when carrying or holding the
stapler.
7. Never carry the stapler by the hose or pull on the
hose to move the stapler.
8. Always wear protective equipment; i.e. safety
glasses, hearing protection and head protection.
9. Do not use a check valve or any other fitting which
allows air to remain in the stapler.
10. Do not place your hand or any other body part in
the staple clinching area or adjustment window
when connecting or disconnecting the air supply.
LUBRICATION & MAINTENANCE
1. Lubricate the stapler prior to initial operation.
2. Disconnect the stapler from the air supply prior to
servicing.
3. Turn the stapler so that the inlet is facing up and put
one drop of high-speed spindle oil, UNOCOL RX22,
or 3-in-1 oil into air inlet. Never use detergent oil or
additives.
4. Operate the tool briefly after adding oil.
5. Wipe off excessive oil at the exhaust. Excessive
oil will damage the O-rings. If inline oiler is used,
manual lubrication through the air inlet is not
required on a daily basis.
AIR SUPPLY AND CONNECTIONS
NOTE: The following illustration shows the
correct mode of connection to the air supply
system which will increase the efficiency and
life of the stapler.
Many air tool users find it convenient to use an inline
oiler to provide oil circulation through their tool. Check
oil level in the oiler daily.
A filter is recommended on your air compressor. Check
the filter and drain on a daily basis.
11. Never point the stapler at yourself or anyone else.

CLEANING THE STAPLER
1. Disconnect the air supply from the stapler.
2. Remove tar buildup with non-corrosive cleaner.
CAUTION! Do not allow solvent to get into the
cylinder or damage may occur.
5. Reconnect the air hose to the stapler.
6. Grasp the handle with one hand on box in line
with the desired staple location. There is a small
projection on either side of the magazine seat as
an aid in locating the position of the staple.
