Electronic Monitor An electronic monitor caution signal indi- cates a condition which could cause serious damage to your unit. Correct cause of signal before continuing operation. CAUTION SYMBOLS & ALARM Battery Charge: Symbol glows (red) in response to low battery charge (below 11.6 VDC). Engine Coolant Level: Symbol glows (red) and alarm sounds if coolant level falls below acceptable operating level.

CHECKS & SERVICES BEFORE STARTING ENGINE (To be performed at beginning of each work shift.) Complete all required maintenance before operating unit. enter these ports, it can shorten the life of o-rings, seals, packing and bearings. When adding fluids or lubricants, refer to lubrication Use extreme caution when checking section of this manual to determine proper type, items beyond your normal reach.

Always stop engine when refueling. Be sure area is free of open flame, sparks or any condition which could cause fuel or fuel vapor to ignite. Check for the presence of a fully charged fire Check fuel level symbol on electronic monitor extinguisher on wall behind operator’s seat.
ENGINE OPERATION NOTE: If engine is being started at beginning of work shift be sure to perform all “CHECKS AND SERVICES BEFORE STARTING ENGINE’’ (pages 19 and 20). Turning ignition switch to START position while engine flywheel is rotating can cause serious damage to engine and/or starting motor. Starting Cummins Engine After engine starts, reduce speed to low idle and Insert ignition key and turn clockwise to RUN...
Normal Engine Operation Be alert for unusual noises or vibration. When an unusual condition is noticed, stop machine in a safe position and shut off engine. Determine cause and correct problem before continuing. Always operate with engine at full throttle to prevent possibility of stalling under heavy Avoid prolonged idling.

ADAPTER ATTACHMENT INSTALLATION Keep boom in fully extended position while installing bucket. Stay clear until bucket adapter has been fitted to bucket as shown in step 2. Digging with a loose or improperly fitted bucket can cause excessive wear, shear adapter bolts or cause loss of bucket.
Page 32
USE YOUR CRAWLER PROPERLY Travel in forward direction whenever possible Never park crawler units on a steep incline or on (with track drive motors at rear). Traveling in the side of a hill. This can distort roller seals and reverse increases wear on sprockets and rollers. cause a loss of lubricant which could ruin the rollers.
Page 33
HOW TO OPERATE THE CRAWLER Practice with travel controls in a safe, open area. Avoid confusion! Before actuating track drive pedals, think about the direction you are facing with respect to the direction the crawler is facing. (Drive sprockets are at rear of crawler). Confusion could cause you to travel in the direction opposite that expected.

LIFTING AND POSITIONING A LOAD Precautions Do not travel with a suspended load. Excavators Do not depend on machine tipping as a warning are not designed for pick and carry lifts. of overload. Some load ratings are based on hydraulic lift capacity, not stability. Sudden swing braking can cause unexpected movement of the load and tip the machine.
Page 39
Perform an unloaded trial run of lift to determine Measure boom height/depth from hole in adapter to maximum boom height/depth and load radius ground level (same level as bottom of tracks). Be required to complete lift. sure to allow or length of chain and height of load. Measure load radius from inner corner of frame at front of cab to vertical load line and add distance to center of rotation (69 inches).

SECURING BOOM Always install shipping pin and secure with hitch pins when preparing machine for transport. Shipping pin is stored in valve compartment. TOWING REFER TO SERVICE MANUAL FOR INSTRUCTIONS FOR TOWING CRAWLER. IF YOU GET STUCK If unit becomes stuck in soft ground you can use the While actuating travel pedals/levers in appropriate boom to help free it.
