STEP 13: Start the vehicle. Running at full throttle, engage the auxiliary hydraulics. Note
the direction of the chain rotation (visible from the operator’s seat). The chain
should be rotating from the bottom to the top. If it is not, reverse the hydraulic
hoses.
STEP 14: Check the hydraulic system for leaks.
STEP 15: After the correct chain rotation has been achieved, count the number of rotations
of the pick-up link per minute.
STEP 16: The number of rotations equals the number of hammer strikes per minute. If you
want to increase the speed, then increase the flow control setting by 1 increment
at a time until you reach the desired number of rotations per minute. DO NOT
exceed the maximum of 50 rotations per minute.
Keep hands and loose clothing clear of the chain drive
assembly. Severe personal injury could occur.
w A R N I N G
Exceeding 0 rotations per minute will cycle the chain faster
than the hammer drops, making the chain come into contact
with the hammer as it is still falling. This will cause severe
damage to the drive assembly.

If the Grapple is installed and the chain is not rotating at all, reverse the
hydraulic hoses.

Remember hydraulic systems are under pressure whenever
the engine is running and may hold pressure after
shutdown. Before connecting or disconnecting hydraulic
hoses, be sure to relieve all pressure by cycling all
hydraulic controls after shutdown.
w A R N I N G
Never check pressurized system for leaks with your bare
hand. wear proper hand and eye protection and use wood
or cardboard when searching for suspected leaks. Oil
escaping from pinhole leaks under pressure can penetrate
skin and create a serious medical emergency. If any fluid
is injected into the skin, gangrene, blood poisoning, even
death may result. Obtain medical attention immediately.
