o
Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures
before beginning work.
o
Warning: Fully lower the crushing platen and remove all hydraulic pressure before beginning any work on the
hydraulic system.
o
Only qualified individuals trained to understand mechanical devices and their associated electrical and hydraulic
circuits should attempt troubleshooting and repair of this equipment
(A) Inspect daily for:
1.) Frayed or damaged wires.
2.) Oil leaks.
3.) Pinched or chafed hoses.
4.) Damage or structural deformation to the cabinet, legs, or door latching mechanism.
5.) Unusual noise or binding, or evidence thereof.
6.) Proper functioning of the upper travel and door switches.
(B) Inspect monthly for:
1.) The hydraulic fluid level. It should be maintained about 1”-1½” below the reservoir’s fill hole with the
crushing platen in the fully raised position. See below for the hydraulic oil specification.
2.) Worn or damaged hydraulic hoses and electrical wires.
3.) Bending of the crushing platen’s hydraulic cylinder rod.
4.) The integrity of the legs’ anchor bolts, and for cracks in the concrete around them.
5.) Condition and tightness of the pushbuttons.
6.) Unusual noises or movement during operation.
7.) All the information/safety/warning labels being in place and in good condition.
8.) The need to clean off dirt and debris.
The oil should be changed if the oil darkens, becomes gritty, or turns a milky color (indicating the presence of
water). Replace with an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F, (ISO 32 at 40°C). Ex:
AW 32 or HO 150 hydraulic oil, or a non-synthetic transmission fluid such as Dexron III. You may use a synthetic
transmission fluid if you flush the system with the synthetic fluid before filling the reservoir.
