SHINGLE GAUGE
This gauge can be used to control shingle spacing. To adjust, push the gauge lever and slide the gauge to the desired
shingle exposure as shown. (Fig 6)
Warning! Disconnect the air supply before making adjustments.
CLEANING THE ROOFING NAILER
Warning! Do not use petrol or similar highly flammable liquids to clean the nailer.
Vapour could be ignited by a spark, causing an explosion. Tar and dirt may build up on the nose and trip lever. This can
prevent correct operation. Remove any buildup with diesel or parafin. Do not dunk the nailer into these solvents beyond
the height of the nail heads, to avoid getting the solvent into the drive cylinder. Dry off the nailer before use. Any oil film left
after cleaning will accelerate the tar buildup, and the nailer will require more frequent re-cleaning.
Note: Solvents sprayed on the nose to clean and free up the trip may have the opposite effect! The solvent may soften the
tar on the shingles and cause tar buildup to be accelerated. Dry operation is better, as noted above.
"DIAL-A-DEPTH™" FASTENER CONTROL ADJUSTMENT (FIG 7)
The DIAL-A-DEPTH™ Fastener Control adjustment feature provides close control of the fastener drive depth; from flush
with the work surface to shallow or deep countersink. First, set the air pressure for consistent drive in the specific work,
then use the DIAL-A-DEPTH™ Fastener Control adjustment to give the disired depth of drive.
DRIVER MAINTENANCE INSTRUCTIONS (FIG 8)
Worn driver causing poor quality or loss of power
● Wear on the driving tip will affect the nail drive, giving symptoms of bent and incompletely driven nails, and damaged
nail heads.
● The driver length may be adjusted to allow the driving tip to be redressed to compensate for wear. Heat and precise
measurement are required. Contact a qualified service technician for this adjustment.
The length setting for a new driver is shown in the Technical Data Table marked ?, column T.
●
Measurement is from the top face of the piston.
Note that the measurement U (see Technical Data Table) from the top of the piston gives the maximum amount the
●
driver may be adjusted to allow re-dressing. Always extend the driver the minimum amount required to allow re-
dressing to restore the driving end; several re-dressings will be possible before this maximum depth is reached.
DIRECTIONAL EXHAUST DEFLECTOR (FIG 9)
Loosen the screw. Adjust to desired exhaust direction and tighten screw.
