JOB SAFETY

It is the owner’s/operator’s responsibility to replace any safety decals that are damaged or missing from the
machine.

Never leave the machine running while it is unattended. Always park the machine in a safe, level area, lower any
work equipment to the ground, move the hydraulic lockout control lever to locked (closed) position, and shut down
the engine before exiting. Secure the machine to prevent tampering by unauthorized personnel.

Before starting any work operations, travel, or maintenance procedures, make sure all personnel are a safe distance
from all points of the machine. Never allow anyone to stand near the machine while it is in operation or under
maintenance or repair.

It is the responsibility of the operator’s employer to conduct periodic safety training and familiarize all personnel
with emergency procedures.

If pedestrians are in the area, sound the horn and proceed slowly.

When working with another person on a job site, make sure that all personnel involved understand all
industry-standard hand signals that are to be used.

The operator shall respond to operating signals from the proper signal person only, but shall obey a stop signal at
any time from anyone.

The operator must always be able to see the work location. If this is not possible, then a signalman must be used. If
visibility becomes blocked for any reason, stop operation immediately.

If the machine is equipped with operator aids, Occupational Safety and Health Administration (OSHA) requires
this equipment to be used when operating the machine.

Personal Protective Equipment (PPE)

Before using personal protective equipment (PPE), make sure it is in good working condition.

Hearing Protection

Prolonged exposure to loud noise can cause impairment or loss of hearing. Wear suitable hearing protection to
protect against loud noises.
