ROUBLESHOOTING

This section provides some basic steps to identify possible causes of trouble, together with troubleshooting

solutions. The FT-20 is a sealed unit. If there are any problems with the PowerPak which go beyond the scope of

these instructions, contact Fatigue Technology Inc. or an FTI Representative who can provide you with the nearest

authorized service center.

WARNING:

To prevent injuries, any repair work or troubleshooting must be done by qualified personnel familiar with

this equipment. Use proper equipment and tools when troubleshooting.

IMPORTANT: Refer to the parts lists (Section 6.0) when using the Troubleshooting Guide.

PROBLEM

CAUSE

SOLUTION

5.1 PUMP WILL NOT START OR WILL NOT STOP REGARDLESS OF TRIGGER POSITION

NOTE:

This is common for new pumps or different puller unit/pump combinations.

(a) Trigger response valve is not

properly adjusted.

(a) While squeezing the trigger of the puller unit,

loosen the brass nut on the trigger response

valve. Adjust the valve pilot in or out until the

desired sensitivity is obtained. Retighten the

brass nut.

(b) Air logic valve is stuck in

position.

(b) The air logic valve is located on top of the pump

just under the shroud. Remove the shroud and

disassemble the valve. Remove the valve spool

and inspect the O-rings and spool body. If the

valve is a Versa



brand valve (gold body),

replace the O-rings as required and remove any

contaminates. If the valve is an I.S.I. brand valve

(black body), the spool will most likely need to

be replaced. Clean any contaminates from the

valve body. Refer to Section 6.0 for valve part

numbers.
