Multicyl User Manual


**BE SURE TO READ THIS ENTIRE MANUAL PRIOR TO USING ANY MULTICYL PRODUCTS**


Section 13: Oil

Occasionally the Multicyl oil level may have to be topped up; but generally the sealed Multicyl oil system should only be replaced when doing a seal change, or after service of one year as part of a preventative maintenance initiative.
- Multicyl uses Shell Tellus 32  hydraulic oil, or an equivalent 150 SSU high grade hydraulic oil can be substituted.


Section 14: Safety

As the simplicity of Multicyl permits non-technical personnel to be involved in machine installations, accident prevention cannot be over-emphasized. Multicyl applications should be properly guarded to comply with all applicable standards for operator safety. Do not let the small size of a Multicyl mislead you - high forces are produced and severe injury may result if proper safety procedures are not adhered to.



The patented self adjusting stroke of Multicyl allows the point of operation opening to be adjusted to 1/4" on many applications. On applications where this is impossible or impractical, Multicyl can provide a two hand anti-tie down safety air control package.


Section 15: Warranty

Multicyl guarantees its products to be free from defect in workmanship for 1 year from date of purchase or 10,000,000 hits. Our warranty is limited to replacement or repair of defective parts at the discretion of Multicyl. This warranty is void if the cylinder is not used in conjunction with a properly maintained filter, regulator, lubricator mounted on the inlet port within 10' of the cylinder. Multicyl can not be held responsible for damage or injury caused by unsafe use or improper application of its products. All guidelines in this manual must be adhered to.


Section 16: Troubleshooting

PROBLEM

CAUSE

SOLUTION

1. CYLINDER DOES NOT PRODUCE FULL FORCE UPON INSTALLATION.

-AIR WITHIN HP HYDRAULIC CHAMBER.

-CYLINDER HAS NOT BEEN PROPERLY BLED.

-AIR PRESSURE AND/OR DELIVERY IS INHIBITED.

-TOOLING DOES NOT HAVE THE NECESSARY DESIGN FEATURES.

-THE OIL IN THE RESERVOIR IS LOW.

SEE SECTION 3

SEE SECTIONS 4 & 8

SEE SECTION 6

SEE SECTION 1

2.CYLINDER CYCLES                SLOWLY.

-RESTRICTION IN AIR LOGIC.

-AIR PRESSURE AND/OR DELIVERY IS INHIBITED.

-QUICK EXHAUST IS BLOCKED OR NOT WORKING PROPERLY.

-TOOLING DOES NOT HAVE THE NECESSARY DESIGN FEATURES.

-THE OIL IN THE RESERVOIR IS LOW

SEE SECTION 4 & 8

SEE SECTION 6

SEE SECTION 3

THE ADDITION OF AN ACCUMULATOR TANK MAY BE REQUIRED

(1)WHERE CYCLE SPEED IS CRITICAL

(2)IN MULTIPLE CYLINDER APPLICATIONS.

3. RAM PISTON DOES NOT  FULLY RETURN OR  RETURNS SLOWLY.

-INSUFFICIENT LUBRICATION IN AIR CYLINDER.

-BLOCKED QUICK EXHAUST.

-MAY ALSO BE CAUSED BY SEAL (18) FAILURE DETECTED BY REMOVING OIL FILLER SCREWS (11)  TO RELEASE AIR PRESSURE IN OIL RESERVOIR (INFREQUENT).

-INCREASE LUBRICATING RATE ON FILTER, REGULATOR, LUBRICATOR UNIT.

-CHECK QUICK EXHAUST, PORT SIZES AND EFFICIENCY.

-REPLACE SEAL KIT.

4 OIL LEAKAGE FROM AIR  CYLINDER VENT HOLE WITH NO CHANGE IN OIL  RESERVOIR LEVEL.

-EXCESSIVE AIR CYLINDER LUBRICATION.

-ADJUST AIR LUBRICATOR (ON FRL) TO CORRECT RATE

5.OIL LEAKAGE FROM AIR      CYLINDER WITH  VISIBLE CHANGE IN

OIL RESERVOIR LEVEL

(A) WORN PISTON ROD SEALS(18) AND (39).

 

(B) SCORED PISTON ROD (LESS FREQUENT).

(A) REPLACE SEAL KIT.

(B) REPLACE PISTON ROD AND SEAL KIT.  CHECK CLEARANCE BETWEEN PISTON ROD AND MEEHANITE BEARING

6.OIL LEAKAGE BETWEEN RAM PISTON AND STRIKER CAP.

(A) DISPERSAL OF PISTON ROD LUBRICATION GREASE.

 

(B) SEAL (47) FAILURE.

(A) NO MAINTENANCE REQUIRED AS GREASE IS NECESSARY FOR CYLINDER LUBRICATION.

(B) REPLACE SEAL KIT.

7.RAM PISTON BOUNCES   BACK AT END OF  STROKE.

EXCESSIVE AIR CYLINDER CYCLE SPEED.

ADD FLOW CONTROL VALVE IN ORDER TO BALANCE AIR CYLINDER SPEED WITH OIL FLOW RATE, OR CYCLE UNDER PRE-LOADED WORKING CONDITIONS.

8.RAM PISTON                    PRODUCES SHORTER     OVERALL STROKE LENGTH.

LOW PRESSURE ADVANCE FORCE EXCEEDED, CYLINDER CHANGING INTO HIGH PRESSURE TOO SOON.

REDUCE RETURN SPRING PRESSURE IN TOOLING.  MINIMUM ADVANCE FORCE OF 400LB. F (.18KN)AT 100 PSI

 (7 BAR) IN LOW PRESSURE STROKE

9. BROKEN ROLL-PIN (33) IN STRIKER CAP.

EXCESSIVE SIDE LOAD UPON RAM PISTON.  NOTE THIS SAFETY FEATURE OF THE SPHERICAL PIVOT POINT ON RAM PISTON IS DESIGNED TO ALLOW MAXIMUM OF 3/4° OUT OF PARALLEL TOOL ACTION BEFORE SHEARING.

REPLACE ROLL-PIN(33) WITH SPRING-LOADED RAM PISTON IN ACTUATED DOWN POSITION.
