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.
