a.) Check powerunit power source.

b.) Control cord may be loose or damaged.

c.) Faulty actuator. Replace.

d.) Check hydraulic couplings; tighten, repair or replace.

2. SLOW OR PARTIAL OPERATION WHEN ACTUATOR IS DEPRESSED

a.) Low hydraulic pressure. Check powerunit, adjust.

b.) Cylinder Piston o'ring (2) could be worn or damaged. Replace.

c.) Solenoid pin in directional valve on powerunit worn or peened over. Replace.

d.) Excessive wear or scoring on moving parts. Check and replace faulty parts.

3.TOOL OPERATES IN REVERSE

a.) Tool stops in back position. Hydraulic hoses are reversed. Correct.

4. HYDRAULIC OIL OVERHEATS

a.) Powerunit motor rotation reversed. Electrical connections reversed. See powerunit instructional
