Troubleshooting

1. Follow 

Pressure Relief Procedure

, page 6, before 

checking or repairing gun.

Reference numbers used in the following procedure 

refer to the 

Parts

 table, pages 8, 10, or 11.

Problem

Cause

Solution

Inconsistent Pump Output

Air and/or lubricant leak between 

the pump and the manifold

1. Check four socket head screws 

(7) to make sure they are tight. 

Torque to 60 to 70 in.lbs. (6.77 to 

7.90 N•m). 

Loose screws could allow air 

and/or lubricant to leak between 

the pump and the manifold.

1. Check for leakage past gasket 

(8). Replace gasket if required.

Jam nut is loose

Check jam nut (9) to make sure it is 

tight against adjustment screw body 

(10). 

If the jam nut is loose, the 

adjustment screw (11) could rotate 

and cause the pump output to 

change. This condition could also 

result in either lubricant leakage or 

air infiltrating the lubricant.

Irregular Lubricant Flow

Air trapped in pump/system

1. Cycle the pump a few times. 

This should bleed out the air.

2. If cycling the pump does not 

bleed out the air, loosen the 

bleed screw (29). Cycle the 

pump a few times.

NOTE:

 Do not remove the ball (28) or 

bleed screw (29).

3. Re-tighten the bleed screw (29).
