Maintenance Instructions

Read and follow all the maintenance instructions pro-

vided in this manual to keep the machine in good oper-

ating condition. Refer to the other materials received

with the unit and to the service bulletins from the

manufacturer for additional instructions on proper main-

tenance and service. Regular inspections and proper

maintenance are essential to preventing accidents and

injuries.

WARNING

Before making any inspection, adjustment,

or repair, disconnect the power source and

block out all moving parts to prevent injury.

WARNING

Keep the machine and the immediate work

area clean. Do not use compressed air to

remove dirt and debris from the machine.

Foreign material may be propelled into the

air and into operator or bystander causing

personal injury.

WARNING

Wear protective clothing, equipment and

eye protection when making any adjust-

ments or repairs to the machine.

Cylinder Maintenance

The unique design of the hydraulically dampened

8” cylinder controls bead loosening, mounting, and

demounting. If the oil becomes low, the machine will

surge at the beginning of its stroke. A special hydraulic

oil must be used.

Filling 8” Cylinders

Fill only with COATS Hydraulic Oil (part #8101411) or an

approved alternate choice (Empak 4061, or Shell Tellus

21). Do not use motor oil or brake fluid.

1. Remove cylinder (part #85608715) and slave cylin-

der (part# 85608739).

2. Remove plug from slave cylinder and fill with oil

until there is no air in either cylinder or connecting hose.
