If it is higher than the SCFM or pressure supplied by your air compressor, a larger compressor is needed to operate accessory. Check and replace air hose, if required. Move unit to a dry well ventilated area. Clean or replace air intake filter. Check belt tension, see Adjusting Belt Tension under Maintenance. Tighten pulley set screw, torque to 85-90 in.-lbs. (9.6-10.2 Nm). Tighten flywheel screw, torque to 14-18 ft.-lbs. (20.0-24.4 Nm). Contact a DeWALT factory service center or a DeWALT authorized service center. Check belt tension, see Adjusting Belt Tension under Maintenance. See Motor Pulley/Flywheel Alignment under Maintenance. Add full synthetic, non-detergent air compressor oil to pump. See Compressor Pump Oil under Maintenance. Drain oil and refill pump with full synthetic non-detergent air compressor oil. Run unit for longer duty cycles. It is recommended to run at high throttle 50-75% of the run time and idle for 25% of the run time. Contact a DeWALT factory service center or a DeWALT authorized service center. 26

or pressure supplied by your air compressor, a larger compressor
is needed to operate accessory.
7
Hole in air hose
Check and replace air hose, if required.
8
Unit operating in damp or humid conditions
Move unit to a dry well ventilated area.
9
Restricted air intake filter
Clean or replace air intake filter.
10
Loose belt
Check belt tension, see
Adjusting Belt Tension
under
Maintenance.
11
Loose pulley
Tighten pulley set screw, torque to 85-90 in.-lbs. (9.6–10.2 Nm).
12
Loose flywheel
Tighten
flywheel
screw,
torque
to
14–18
ft.-lbs.
(20.0–24.4 Nm).
13
Carbon build-up in pump
