Always check equipment for proper operation before each use,
making sure safety devices are in place and operating properly.
DO NOT alter or modify any part of the equipment as this may
cause a malfunction and result in serious bodily injury.
ATTACHING HYDRAULIC MOTOR TO PUMPTUBE
1. Tightly Attach Tie Rods (Item 38) to the Mounting Plate (Item 37).
(Use short threaded end of tie rods).
2. Mount hydraulic motor on top of pumptube outlet body and tightly
connect pumptube coupling nut to Piston Rod (Item 29).
3. Hand tighten tie rods to the pumptube with four Nuts (Item 39)
supplied with hydraulic motor.
4. Connect hydraulic supply and return lines and slowly cycle pump
several times, using only enough pressure to operate the pump
without stalling
NOTE: Air in the hydraulic motor may cause slow or erratic shift-
ing during the rst few cycles after connecting the hydraulic lines.
5. Stop the pump on an "up" stroke and tighten the four nuts to
securely fasten the hydraulic motor to the pumptube.
To reduce the risk of serious bodily injury or property damage.
NEVER exceed the maximum uid working pressure of the low-
est rated system component.
OPERATING PRECAUTIONS
• Use Lincoln replacement parts to assure compatible pressure
rating
• HEED ALL WARNINGS.
• Be sure material hoses and other components are able to with-
stand hydraulic pressures.
• Do not operate hydraulic motor continuously at speeds in excess
of 75 cycles per minute.
• Disconnect hydraulic line from hydraulic motor when system sits
idle for long periods of time.
• SERVICING. Before servicing hydraulic motor be sure to
carefully bleed pressure off of the system and disconnect the
hydraulic supply lines.

TROUBLESHOOTING
Problem Possible Cause Solution
Hydraulic Motor does not operate. Restricted of inadequate hydraulic supply.
Check that hydraulic supply has sufcient
pressure and ow to operate motor.
Restricted hydraulic return to tank. Check return line for restrictions.
Piston moves to top of stroke and does
not shift.
Damaged O-rings (items 20 & 21) Check for external leakage at Cylinder Cap (Item
16) and manifold interface. Replace O-rings if leak
is detected.
Damaged check valve components (Items
14, 17 & 18).
Check for external leakage or damaged parts.
Replace if needed.
Worn or damaged Piston Cup (Item 24) Check and replace if needed.
Worn or damaged Cartridge Valve (Item 11). Check and replace if needed.
Piston mums to bottom of stroke and
does not shift. Damaged O-rings (Items 21 & 32).
Check for external leakage at Cylinder Head (Item
