GENERAL MAINTENANCE INFORMATION
To prevent minor irregularities from developing into serious conditions, several other services
or checks are recommended for the same intervals as the periodic lubrication. The purpose of
these services or checks are to ensure the uninterrupted and safe operation of the machine
by revealing the need for adjustment caused by normal wear.
Prior to conducting any maintenance work, ensure that the following
instructions are observed:
1. Park the machine on firm level ground.
2. Shut down the engine and allow it to cool.
3. Disconnect battery power (as required) by removing the black ground
terminal(s). Cover exposed terminals before working on the machine's
electrical system. Certain troubleshooting procedures will require that battery
terminals not be removed.
4. Following shutdown, allow hydraulic oil pressures to fall before working on
hydraulic hose installations.
5. Thoroughly wash all fittings, caps, plugs, etc., with nonflammable, nontoxic
cleaning solution before servicing, to prevent dirt from entering while
performing the service.
