OWNER SERVICE

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.

„Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.

„Make sure that all operating and service person- nel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gan- grene, serious injury, or death will result. CON-

TACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.

„Before working on backhoe, extend boom and dipperstick and place bucket on ground. Make sure that all system pressure has been relieved by oper- ating controls before maintenance, service, or dis- connecting any hydraulic lines.

CAUTION

„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.

OPTIONAL AUXILIARY PUMP AND HYDRAULIC SYSTEM

IMPORTANT

■Fill with clean oil. Do not mix oil types or grades.

Daily, check the fluid level in reservoir with filler cap dipstick. Contamination will shorten the life of hydraulic system components. Change oil and filter after first 20 hours of operation and then every 200 hours of opera- tion or annually, whichever occurs first. In extremely dusty or dry conditions, more frequent changes may be necessary. System capacity is approximately 5 to 5-1/2 US gallons.

Engage PTO and run at idle for 5 minutes, then check oil level. Add fluid as necessary.
