Connect the tool to an air compressor using a 3/8” I.D. hose. Make
sure the hose has a rated working pressure exceeding 200 PSI and a
female quick coupler. (See Fig. 3)
Regulate the air pressure to obtain 80 PSI at the tool. Check the
operation of the contact safety trip mechanism following the
instructions in this manual. (See Fig. 4)

Fig 6)
Reconnect the air supply to the tool.
Test for proper nail penetration by driving nails into a sample piece of
wood. If the nails do not achieve the desired penetration, check that
pressure is adjusted to at least 100 psi. Then adjust depth stop on back
of roofer until desired penetration is reached. (See Fig. 7) Do not
exceed 120 PSI at the tool.

platform can be moved up and down to three settings. To change
setting pull on the post and twist to the correct step. (See Picture 1)
Failure to adjust magazine height for nail size may
damage the nail feed mechanism.
Place the coil of nails over the post in the magazine. Uncoil enough
nails to reach the feed pawl. Place the first nail in front of the front
tooth on the feed pawl in the driver channel. The nail heads must be in
the slot in the nose. (See Picture 2)
Swing the latch door and magazine cover closed. Check that the latch
pin engages when released and that the magazine cover is behind the
latch.

Disconnect the tool from air supply.
Pull open cap canister lever and remove empty paper spool. Remove
the tape from the end of the cap strap on the spool. Push the spool over
the canister spindle and feed the caps into the track. (See Picture 3)
