MAINTENANCE
WARNING:
All inspection and maintenance procedures must be performed after the equipment has been re-
moved from service. Failure to heed this warning may result in personal injury and / or property damage.
1. Lightly oil all pins to prevent corrosion. The pins that must be oiled are the leg positioning pins, boom extension pin,
and the cylinder retaining pins.
2. Lightly oil the chain, hook, and any appropriate part of other load capturing devices to prevent corrosion.
3. If equipped with the AHP-100 air pump, add a few drops of air tool oil to the air line and operate the pump. This will
help lubricate the air piston and prevent moisture in the air line from corroding the inside of the air motor.
4. Inspect the condition of all decals on the crane. They should be legible and easy to read. If they become hard to
read, clean with a mild soap and water solution or replace immediately.
Structural Inspection
WARNING:
Equipment must be removed from service and inspected for damage immediately if subjected to an
abnormal shock or load. Failure to heed this warning may result in personal injury and / or property damage.
WARNING:
The owner must inspect, or appoint a knowledgeable person to inspect the crane for signs of dam-
age, corrosion, excessive wear, oil leaks, air leaks (if equipped with AHP-100 air pump), abnormal operation, or
any other potential problem. NEVER use a crane that appears to be damaged in any way. If any irregularities or
problems are detected during an inspection, the crane must be removed from service immediately and repaired.
Contact customer service at the address and numbers shown on the back cover of this manual to report any
problems.
Use the following procedures to inspect the crane for wear or damage:
Inspect Crane Frame, Chain, and Hook
1. Check the crane for corrosion, cracked welds, or any other damage such as cracks, chips, dents, marring, or other
deformation. If any corrosion or damage is discovered, immediately remove the crane from service and contact
customer service using the contact information found on the back cover of this manual.
2. Check the crane’s chain and hook or other load capturing device for corrosion or any damage such as cracks,
chips, dents, marring, or other deformation. Keep all load capturing devices of the crane in good working order.
If they are damaged or are excessively corroded, replace. Use only devices supplied by the manufacturer of the
crane.
Inspect All Hydraulic Components
1. Inspect the hydraulic hose and fittings for any signs of wear, damage, or oil leaks. NEVER use a damaged hose or
fittings.
WARNING:
Do not bend the hydraulic hose through less than a 5 inch radius.
DANGER:
Keep the hydraulic system away from flames and heat. NEVER impact the hydraulic system in any
way.
2. Make sure the release knob operates properly.
3. Inspect the cylinder and cylinder rod for any signs of wear, damage, or oil leaks. The cylinder rod should be straight
without any gouges, scratches, or marks. The cylinder must be free of dents, gouges, or other damage. NEVER
use a cylinder that is damaged in any way.
Inspect All Air Components (If equipped with AHP-100 only)
WARNING:
This press is designed to operate with air pressure of 95 psi to 200 psi. Do not exceed this rating.
1. Check the air line and fittings for signs of wear, damage, or leaks. Replace the air line if any damage is found.
2. Make sure that the air valve is working properly. To prevent the risk of serious injury, the boom must stop immedi-
ately when the air valve is released.
