TROUBLESHOOTING

TOOL TROUBLESHOOTING

Your pneumatic fastening tool has been designed for long life and trouble-
free operation.  However, if operating problems arise, please use the
troubleshooting information below to determine how to remedy the prob-
lem.

TROUBLESHOOTING

FASTENER DRIVING PROBLEMS

Always disconnect tool from air supply before performing any service on
tool. Correcting a problem while the tool is pressurized may result in
injury from fastener discharge or tool operation.

DANGER

Tool leaks air.

Check for source of leak, and tighten fittings
and screws as required.  Discontinue using
tool if air leaks at trigger area or from cap
exhaust.  Contact your dealer.

Tool operates, but no
fastener is driven.

Tool won’t operate - nail
jammed in tool nose,
preventing tool from
operating.

Remove jammed fastener.  Check magazine
for incorrect, bent, or loose fasteners, and
discard.  Reload using Grip-Rite™ nails.

Check magazine for jammed fastener.  Clear
jam and reload magazine.  Check nail strip for
smooth feeding in magazine.

Fasteners do not drive
completely.

AT COMPRESSOR:  Increase air pressure.
Do not exceed 110 psi/7.6 bar

Fasteners do not drive
completely when
driving in quick succes-
sion.

Inadequate air flow.  Use larger diameter hose.
Use compressor with larger storage tank.
Keep hose lines short.  Check air hose for
kinks or other restrictions.

Fasteners drive too
deeply.

AT COMPRESSOR:  Reduce air pressure.
(Do not reduce below 70 psi/4.8 bar.)

PROBLEM

CORRECTIVE ACTION

Fasteners do not drive
completely after air
pressure is increased.

Driver blade worn or broken.  See dealer for
replacement.

FASTENER DRIVING PROBLEMS

AT TOOL:  Turn adjustment dial to increase
nail drive depth.  Add 2 - 3 drops of air tool oil
to inlet.

AT TOOL:  Turn adjustment dial to decrease
nail drive depth.

TOOL CHECKS

Keep your nailer in top working condition by checking it daily.  See your
Grip-Rite™ dealer for service if part or operating problems are found.  Never
use a malfunctioning tool - it could result in serious injury.

Workpiece Contact & Trigger

Check workpiece contact for proper operation before each use.  Workpiece
contact must move freely and return to extended position when lifted from
workpiece.  Trigger must operate freely.

Daily Inspection

• Check for broken, damaged, or excessively worn parts, and repair

or replace as needed.

• Check for air leaks at trigger, cap, and nose.  Disconnect tool from

air supply immediately if leaks are present, and see dealer for
service.

• Make sure all screws are tightened securely.
