Risk of damage to the hoist gears.
The waste oil must be checked for abrasion particles. This test is used to
detect any damage at an early stage;
Risk of environmental damage due to leaking consumables.
Always let consumables drain into suitable receptacles. Wipe up any con-
sumables that have leaked.
Store/dispose of consumables and any soaked equipment properly.
Ask about the applicable regulations.
During filling, the oil spreads only slowly in the hoist. The oil level therefore
rises quickly in the standpipe at first, then drops slightly and then eventually
rises again to its true level.
