MAINTENANCE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
NEVER GO UNDERNEATH EQUIPMENT. Never
place any part of the body underneath equipment
or between moveable parts even when the engine
has been turned off. Hydraulic system leak-down,
hydraulic system failures, mechanical failures, or
movement of control levers can cause equipment
to drop or rotate unexpectedly and cause severe
injury or death.
• Service work does not require going under-
neath.
• Read Operator's Manual for service instruc-
tions or have service performed by a qualified
dealer.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate
