Checking the oil
H
Check the waste oil for abrasion particles or have it tested in a laboratory:
• Pour the waste oil through a clean filter mat.
• Examine the oil or the residues on the filter mat using a magnifying glass.
If you find abrasion particles or solid materials on the mat, the hoist gear
must be dismantled and inspected by the manufacturer.
H
Some abrasion particles may appear in the first oil filled. If you notice
abrasion particles during the first oil change (after 200 oper. hrs.), first
consult
Manitowoc Crane Care before introducing any specific measures.
G
Risk of accidents from falling load!
If this inspection is not performed, there is a risk of damage to the hoist gear
which could lead to the load falling.
