Maintenance - Campbell Hausfeld HU3508 Serie Mode D'emploi

6. Adjust regulator to proper pressure for tool or tire.
Operate tool per instructions.
As air is depleted from the tank by use of a tire chuck, tool,
etc., the compressor will restart automatically at its preset
"cut-in" pressure. When a tool is being used continuously, the
compressor will cycle on and off automatically.
7. Turn switch to OFF position, unplug power cord and drain
tank of air and moisture when finished using compressor.

Maintenance

Disconnect, tag and lock out power source,
then release all pressure from the system before attempting
to install, service, relocate or perform any maintenance.
Check compressor often for any visible problems and follow
maintenance procedures each time compressor is used.
ASME SAFETY VALVE
Do not remove or attempt to adjust the
safety valve!
Check the safety valve by performing the following steps:
1. Plug the compressor in and run until shut off pressure is
reached.
2. Wearing safety glasses, pull the ring on the safety valve to
release pressure from compressor tank. The safety valve
should remain open. Use your other hand to defl ect fast-
moving air from being directed toward your face.
3. The safety valve should automatically close at
approximately 40 psi - 50 psi. If the safety valve does not
allow air to be released when you pull on the ring and
remain out, or if it does not close automatically, it MUST
be replaced.
Safety valve must be replaced if it
cannot be actuated or it leaks air after ring
is released.

valve. Deflect escaping air by shielding valve with one
hand as you pull ring with other hand.) Pull ring until tank
is empty.
A large amount of fast moving air will
be released when the safety valve is
opened with pressure in the tank. Wear ANSI approved Z87.1
safety glasses.
2. Drain moisture from tank by opening drain valve
underneath tank. Tilt tank to remove all moisture.
3. Clean dust and dirt from tank, air lines and pump cover
while compressor is still OFF.
INTAKE AIR FILTER MAINTENANCE
Removal, Inspection and Replacement (Figure 6).
The intake filter element should be removed and checked
periodically. A clogged intake filter can decrease compressor
performance and
cause the compressor
to overheat.
1. Unscrew air fi lter
from compressor
2. Remove the fi lter
cover and fi lter
element. Inspect
each piece.
3. If the fi lter

element is dirty
or clogged,
replace it.
4. Reinstall fi lter, cover, and element.
IMPORTANT: Locate unit as far from spraying area as hose will
allow to prevent overspray from clogging filter.
END OF OPERATION/STORAGE
1. Turn AUTO/OFF switch to the OFF position.
2. Unplug power cord from wall outlet and wrap around
handle to prevent damage when not in use.
3. Wearing safety glasses drain tank of air by pulling the ring
on the safety valve. Use other hand to deflect fast moving
air from being directed toward your face.
4. Drain tank of condensation by opening drain valve on
bottom of tank. Tank pressure should be below 10 psi
when draining tank.
5. Air hose should be disconnected from compressor and
hung open ends down to allow any moisture to drain.
6. Compressor and hose should be stored in a cool, dry place.
