Maintenance Tips

•  Adjust fluid level in reservoir as necessary.

•  Encourage all operators to report any malfunction or accident that may have damaged the   
 

hydraulic system or component.

•  Do not attempt to weld any broken motor component. Replace the component with original   
 

equipment only.

•  Do not cold straighten or bend any motor part.

•  Prevent dirt or other foreign matter from entering the hydraulic system. Clean the area  

 

 

around the filler caps before checking oil level.

•  Investigate and correct any external leak in the hydraulic system no matter how minor.

•  Comply with manufacturer's specifications for cleaning or replacing the filter.

Do not strike or drop the motor on the shaft end. This will cause internal 
damage.

CAUTION

Do not weld, braze, solder or in any way alter any motor component.

CAUTION

Maximum operating pressure must not exceed recommended motor pressure 
capacity.

CAUTION

Always carefully inspect any system component that may have been struck or 
damaged during operation or in an accident. Replace any component that is 
damaged or that is questionable.

CAUTION

Do not force any coupling onto the motor coupling shaft as this could damage 
the unit internally.

CAUTION

Parker Hannifin Corp. extends close technical cooperation and assistance. If problems occur 
that you cannot solve, please contact our Parker Technical Service Representative or local 
Parker Distributor. See the back cover of this manual for our address, phone and fax numbers.
