Continued on next page.

 The filter element is clogged. Replace the filter

element.

 Check the lead-in pressure and tank lines for any

obstructions. Also check the quick disconnects to

see that they are securely tightened. A bad quick

disconnect can cause the Hawkjaw to malfunction.

Replace the faulty connector.

 The air pressure is low. Increase the air pressure to

the HawkJaw.

 The hydraulic pressure is low. Increase the hydrau-

lic pressure. Do not increase the pressure over 2600

psi, or the hydraulic fluid will pass over the relief

valve and heat up the hydraulic fluid. This will cause

damage to the HawkJaw and to the pump, and will

severely shorten component life.

 Check to make sure the hydraulic power unit is

producing 2600 psi at 20-35 gpm.

 Check to make sure the hydraulic power unit pres-

sure compensator setting is at 2600 psi.

 There ia s leak in the hydraulic system. Check for

visual leaks in the hoses, fittings, manifolds, cylinder

rod heads, or cylinder rod wipter seals. Replace

necessary components.

 There ia s leak in the hydraulic system. Operate the

Hawkjaw. Feel the outside of all actuators. If a

portion of the cylinder surface is too hot to leave

your hand on the cylinder, the leak is inside the

cylinder. Replace the cylinder seals. If necessary,

replace the cylinder.

Hawkjaw performance and

speed not up to par.

 The Drive motor is worn out. With filtered hy-

draulic fluid through a Hawk approved filter, the

Drive motor is a long term wear item. If all other

rotating members on the spinner work, inspect the

rotating group, bearings and seals for wear. Replace

where necessary.
