Double-acting cylinders must have both couplers connected.
Fully hand-tighten all couplers. Loose coupler connections can block the
fl
ow of oil.
2. Bleed air from the cylinder as shown below.
Single-acting cylinders: Position the cylinder so that the plunger is pointed down and the
cylinder is lower than the pump. Fully extend and retract the cylinder 2 or 3 times.
Double-acting cylinders: Lay the cylinder on its side with the couplers facing up. Fully
extend and retract the cylinder 2 or 3 times.
Collar threads are rated for the full capacity of the cylinder when fully engaged.
OPERATION
O
O
DO NOT HANDLE PRESSURIZED HOSES.
Escaping oil under pressure can penetrate the skin, causing
serious injury or death. If oil is injected under the skin, see a
doctor immediately.
Operate the hydraulic pump to advance and retract the cylinder.
Some single-acting cylinders are spring-return, others are load return.
The speed of retraction is affected by the length of the hose and other
restrictions in the line. Double-acting cylinders are powered in both
directions by the pump.
The cylinder stop ring is designed to take the full load. However, to
reduce cylinder wear, use less than full stroke when possible.
MAINTENANCE
C
1. Use only Simplex oil with these cylinders.
2. Use dust caps when cylinders are disconnected from the hose.
Keep entire cylinder clean to prolong cylinder life.
3. Store cylinders up-right and fully retracted to prevent seal
distortion..
