MAINTENANCE
Failure to set the vehicle emergency
brake and chock wheels before
performing service can cause severe
personal injury or property damage.
Disconnecting fluid or pressure
containment components during pump
operation can cause serious personal
injury, death or major property damage
Hazardous pressure
can cause personal
injury or property
damage
Hazardous pressure

Failure to relieve system pressure prior
to performing pump service or
maintenance can cause personal injury
or property damage.
If pumping hazardous or toxic fluids,
system must be flushed prior to
performing service
Hazardous pressure

Hazardous or toxic
fluids can cause
serious injury.
Failure to disconnect and lockout
electrical power or engine drive before
attempting maintenance can cause
severe personal injury or death
Operation without guards in place can
cause serious personal injury, major
property damage, or death.
Hazardous
machinery can
cause serious
personal injury.
Do not operate
without guard
in place
NOTICE:
Maintenance shall be performed by qualified technicians only,
following the appropriate procedures and warnings as presented in this manual.
STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.
LUBRICATION
NOTICE:
To avoid possible entanglement in moving parts do not
lubricate pump bearings,
hydraulic adapter coupling or
any other parts while the pump is running
.
NOTICE:
If pumps are repainted in the field, ensure that the grease
relief fittings (76A) are functioning properly after
painting. Do NOT paint them closed. Remove any
excess paint from the fittings.
Lubricate the ball bearings, and hydraulic motor couplings (if
equipped), every three months at a minimum.
Recommended Grease:
Mobil® - Mobilgrease XHP222,
Exxon® - RONNEX MP Greas
e, or equivalent.
Manual Greasing Procedure:
1. Remove the grease relief fittings (76A) from the bearing
covers (27A) or hydraulic motor adapter (135).
2. Apply grease with a hand gun until grease begins to
escape from the grease relief fitting port.
3. Replace the grease relief fittings (76A).
DO NOT overgrease pump bearings. While it is normal for
some grease to escape from the grease tell-tale hole after
lubrication, excessive grease on pumps equipped with
mechanical seals can cause seal failure.
Auto Greasing Systems:
If end users choose to install/use auto greasing systems on
their trucks, that system MUST be adjusted to match the
pump requirements. Over-greasing will cause seal failure –
under-greasing will cause bearing failure.
