INSTALL BUCKET

8", 12", and 16" buckets are available with this back- hoe. Remove pivot pins (7) from end of bucket link (5) and dipperstick (1). Attach bucket (3) to bucket link and dipperstick with pivot pins (7) and secure with bolts (10) and lock nuts (11).

INSTALL HYDRAULIC HOSES

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.

Make sure shields and guards are properly installed and in good condition. Replace if damaged.

Power to the backhoe is supplied directly from the trac- tor hydraulic system. A hydraulic requirement of 3.5 gallons per minute and 1780 psi is necessary to oper- ate the backhoe efficiently. 3/8" diameter hoses (SAE 100 R1 with 3000 psi working pressure) should be used to connect the hydraulic source to the backhoe valve. These hoses must be long enough to allow ease of removal or attachment of backhoe. Hoses must include external shielding to prevent oil from spraying on operator if hose fails.

Refer to the sub-frame mounting kit manual for specific installation instructions.

INSTALL BACKHOE BRACKETS

Remove backhoe from pallet and position on level sur- face. Install backhoe brackets found in the sub-frame mounting kit.

ATTACH BACKHOE TO TRACTOR

Back tractor as near as possible and center on back- hoe. Refer to the sub-frame mounting kit manual for instructions on connecting hydraulic hoses and attach- ing the backhoe to the tractor.

After cycling backhoe through its operating range, stop tractor and check the oil level in the tractor transmis- sion.
