ADDITIONAL SAFETY INSTRUCTIONS
Fig.6
A. Never exceed the maximum load capacity of the ram.
Do not over extend the ram, as it is possible to force
the plunger out of the top of the ram.
B. When coupler valves are disconnected always insert
the dust cap to keep the oil lines clean.
C. If the load is not centered to the ram plunger, pump
carefully. If you have to use excessive pressure to
pump the ram, stop the operation and adjust the set-
up so that the load is more central. This should decre-
ase the effort required.
D. Do not drop any heavy objects onto the hose, and do
not allow the hose to kink. Always allow clearance
for the hose to avoid damage to the hose and coup-
lers.
E. Keep the equipment away from heat or fire, as this
may damage or weaken the equipment.
