MAINTENANCE AFTER THE FIRST 100 SERVICE
HOURS (FOR NEW MACHINE)
1. Replacing the line filter element
Remove the filter with a filter wrench and replace
it with new one.
Before replacing the filter, be sure to open the
hydraulic oil tank to bleed the filter.
2. Cleaning the pilot filter
Remove the plug from under the floor plate with a
wrench (width across flats:27 mm) and pull out the
element.
Clean the element with cleaning oil and remove all
dirt.
3. Cleaning the suction filter
Remove the suction filter from the hydraulic oil
tank. Clean the filter with diesel fuel or kerosene
to remove the dirt. If the strainer is broken,
replace it with new one.
To reinstall the lid, set the O-ring securely into the
flange groove in order to prevent a leak of hydraulic
oil.
Do not perform this operation while the hydraulic oil
is still hot, to avoid being burned.
