Tips for Maintaining the Torqmotor™ Hydraulic System
• Adjust fl uid 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 Torqmotor™ component. Replace the component with original equip-
ment only.
• Do not cold straighten, hot straighten, or bend any Torqmotor™ part.
• Prevent dirt or other foreign matter from entering the hydraulic system. Clean the area around and the fi ller
caps before checking oil level.
• Investigate and correct any external leak in the hydraulic system, no matter how minor the leak.
• Comply with manufacturer’s specifi cations for cleaning or replacing the fi lter.
CAUTION: Do not weld, braze, solder or any way alter any Torqmotor™ component.
CAUTION: Maximum operating pressure must not exceed recommended Torqmotor™ pressure ca-
pacity.
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 Torqmotor™ coupling shaft as this could damage the
unit internally.
