SAFETY NOTES-POSITIVE AND NEGATIVE DERRICK OPERATION
Potential safety hazards exist largely due to the human element. The following listed positive and negative
safety notes must be followed during every workday condition when operating the M876 truck.
Your greatest assets on-the-job are care, caution and common sense.
POSITIVE SAFETY NOTES
DO
...Think of Safety.
...Position your M876 truck on solid, level ground, as close as possible to the work area.
...Lower all four outriggers whenever you use the derrick.
...Make sure everyone is clear of outriggers when you lower them.
...Warm up the hydraulic system In cold weather. Engage the PTO and allow the hydraulic pump to run for five
minutes, at low speed.
...Be aware of any overhead obstructions before you raise the derrick.
...Frequently, check the winch and auger windup cables. A frayed or weak line could cause someone to be hurt.
...Make sure everyone is clear before you release the auger lock.
...Avoid jerking, or any sudden moves of the control levers, that causes the equipment to jerk. Operate your
control levers smoothly and gradually.
...Keep the hydraulic system clean and full.
...Fasten your safety belt onto the loop on the basket when you're in it.
...Keep the derrick leg and extensions clear of the traffic lanes to avoid being hit by passing vehicles.
...Face the direction in which you are moving. Be on the 'lookout' for unforeseen hazards.
...Wear a hard hat, and follow the safety rules.
