Know the maximum height and the maximum reach of your machine. Serious injury or death by electrocution can occur if the machine or the work tools are not kept a safe distance from electrical power lines. Keep a distance of at least |
For safety, one of the following may require a greater distance:
- Local codes
- State codes
- Requirements of the job site

When swinging into a ditch, do not use the ditch to stop the swinging motion. Inspect the machine for damage if the boom is swung into a bank or an object. Repeated stopping by an object can cause structural damage if the boom is swung into a bank or an object. With certain boom-stick-bucket combinations, the bucket or worktool can hit the cab and/or the front structure of the machine. Always check for interference when first operating a new bucket or a new work tool. Keep the bucket or work tool away from the cab and away from the front structure during operation. Whenever the tracks of the machine raise off the ground while digging, lower the machine back to the ground smoothly. DO NOT DROP OR AVSCH IT WITH THE HYDRAULICS. Damage to the machine can result. |
Know the location of any buried cables. Mark the locations clearly before you dig.
Consult your AVSpare dealer for special bucket tips that are available for use in severe applications.
Move the machine whenever the position for digging is not efficient. The machine can be moved forward or backward during the operating cycle.
When you operate the machine in close places, utilize the bucket or other work tools to perform the following functions:
- Pushing the machine
- Pulling the machine
- Lifting the tracks
Use a comfortable travel speed while you operate the machine.
Operating efficiency can be increased by using more than one machine control to perform a task.
Never swing a load over a truck cab or workers.
Position the truck so that material can be loaded from the rear of the truck or from the side of the truck. Load the truck evenly so that the rear axles are not overloaded.
An oversize bucket or a bucket that is equipped with blade type side cutters should not be used in rocky material. These types of buckets slow down the cycle. Damage to the bucket and to other machine components could result.

Do not use the swing force to perform the following operations:
- Soil compaction
- Ground breaking
- Demolition
Do not swing the machine while the bucket tips are in the soil.
These operations will damage the boom, the stick, and the bucket and the operations will reduce the life of the equipment.

| Illustration 2 | g00818699 |
Do not use the dropping force of the bucket as a hammer. This will bring excessive force on the rear of the machine. Possible damage to the machine could result.
| |
| Illustration 3 | g00818702 |
If the cylinder is operated at the end of the stroke during operations, excessive force will occur on the stopper on the inside of the cylinder. This will reduce the life of the cylinder and structures. To avoid this problem, always leave a small margin of play when the cylinder is operated.

| Illustration 4 | g00818707 |
While the bucket is in the ground, do not use the travel force for any excavation. This operation will cause excessive force on the rear of the machine.

| Illustration 5 | g00818711 |
Do not use the dropping force of the rear of the machine for excavation. This operation will damage the machine.

When deep holes are dug, do not lower the boom so that the bottom side of the boom touches the ground.
When deep holes are dug, do not allow the boom to interfere with the tracks.
