--- each time the hydraulic oil is changed.
IMPORTANT: This upper tank area must be very clean
prior to beginning this procedure. Failure to clean the
top of tank may lead to hydraulic system problems
due to system contamination.
Two suction filters are located on the bottom of the hydraulic
oil tank. Clean the suction filters when changing hydraulic oil.
1. After draining hydraulic oil, remove cover (1) with
gasket. Remove lock nuts (2) and washers (3), and
remove suction filters (4) from the oil pipe.
When removing the suction filter, take care not to allow
trapped dust to fall into tank.
IMPORTANT: A few small particles in the strainer is
normal. Large metal, rubber pieces, or a large amount
of fine particles is abnormal. If found, contact your
authorized dealer.
2. Clean the suction filter and the hydraulic oil tank inside
with cleaning solvent. Swab out cleaning oil with a lint
free cloth.
3. Install cleaned suction filters (4) to the oil pipe, and
tighten lock nuts (2) with washers (3).
