Preventive Maintenance Continued
8. Hose Connections
:To prevent personal injury from leaking hydraulic fluid, seal all hydraulic connections
with a high-quality, non-hardening, pipe thread sealant.
IMPORTANT: Sealant tape or non-hardening sealer tape can be used to seal hydraulic
connections if only one layer of tape is used. Apply tape carefully, two threads back, to prevent
it from being pinched by the coupler and broken off inside the system. Loose pieces of sealant
could travel through the system and obstruct the flow of fluid or cause jamming of precision-fit
parts.
9. Storage
Store the unit in a dry, well-protected area where it will not be exposed to corrosive vapors, dust,
or other harmful elements� If a unit has been stored for an extended period of time, it must be thoroughly
inspected before it is used�
10. Checking Brushes on Universal Motors

A� Remove the metal brush cover plates�
B� Remove the brush holder caps and brush assemblies�
