goggles. Use in well-ventilated areas. Keep away from open flames and other sources of igni-

tion.

Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle

pressure when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when

cleaning components. DO NOT direct compressed air against human skin. Failure to follow

this warning may result in serious injury or death. Make sure air stream is directed away

from user and other personnel in the area. To prevent injury, user must wear protective gog-

gles or face shield.

Thoroughly clean all parts in solvent cleaning compound.

clean oil.

During assembly, ensure reference marks for end cover, pump and front pump body are in

alignment.

During assembly, all components must be installed in correct direction of pump rotation.

Pump rotation as seen from splined end of shaft is to the left.

Install new large O-ring (35) in front pump housing (3).

Turn front pump housing (3) over and install new felt ring (34) and seal (33) in front pump housing, with spring-loaded

lip toward pump bearing.
