PERIODIC INSPECTIONS & MAINTENANCE INSTRUCTIONS
ALWAYS EMPTY THE CRUSHER BEFORE INSPECTING OR PERFORMING MAINTENANCE ON IT.
(A) Before each use, inspect the crusher and remove it from service if any of the following
issues are observed:
1.) Frayed wires;
2.) Oil leaks;
3.) Pinched or chafed hoses, loose fittings;
4.) Structural deformation of frame;
5.) Unusual noise or binding
(B) Monthly Inspections
1.) Check oil level. Oil should be 2" to 2½" below the top of the tank with the
cylinder in the fully retracted position. Add as necessary.
2.) Check for oil leaks.
3.) Check for worn or damaged hydraulic hoses, electrical wires, and cords.
Repair as necessary.
4.) Cycle the crusher and listen for unusual noise.
5.) Make sure all warning labels are readable and in place according to the
diagram on p. 12.
6.) Remove dirt and debris.
(C) Yearly Inspection
Change the hydraulic oil at least once per year. However, because the oil
should be changed as soon as it darkens, looks milky, or becomes gritty, oil
changes might be required more frequently than every 12 months.
After draining the oil from the reservoir, flush the reservoir before refilling it.
If the oil looks milky, water is present and the oil should be changed
immediately.
Recommended hydraulic oil: Purity ISO AW-32 Hydraulic fluid or equal.
