Safety Practices
1.6 Model 644E-42/944E-42 Rev. 6/04
1.6.3 General Hazards
SOLVENTS: Only use approved solvents, and solvents
that are known to be safe for use.
HOUSEKEEPING: Keep the work area and operator’s
cab clean and remove all hazards (debris, oil, tools, etc.).
FIRST AID: Immediately clean, dress and report all
injuries (cuts, abrasions, burns, etc.), no matter how
minor. Know the location of a first-aid kit, and know how
to use it.
CLEANLINESS: Wear eye protection, and clean all
components with a high-pressure or steam cleaner
before attempting service.
When removing hydraulic components, plug hose ends
and connections to prevent excess leakage and
contamination. Place a suitable catch basin beneath the
vehicle to capture fluid run-off.
1.6.4 Operational Hazards
OPERATIONAL CONSIDERATIONS: Before operating
the vehicle, carefully read, understand and follow the
Owners/Operators Manual.
ENGINE: Stop the engine before performing any service.
DANGEROUS START: Place Accident Prevention Tags
on both the ignition switch and steering wheel before
attempting to perform any service or maintenance.
Disconnect battery leads. Place a warning sign on
vehicles that are dangerous to start, if leaving the vehicle
unattended.
VENTILATION: Avoid prolonged engine operation in
enclosed areas without adequate ventilation.
RADIATOR CAP: Always wear steam-resistant, heat-
protective gloves when opening the radiator cap. Cover
cap with a clean, thick cloth and turn slowly to the first
stop to relieve pressure.
SOFT SURFACES AND SLOPES: NEVER work on a
vehicle that is parked on a soft surface or slope (inclined
ground or hill). The vehicle must be on a hard, level
surface with the wheels blocked when performing any
service. Obtain assistance, block all wheels, and add
supports if necessary, before beginning any work.
SUPPORTS AND STRAPS: Install safe, stable supports,
slings or straps, beneath or around a component or
structural member before beginning any work.
FLUID PRESSURE: Before loosening any hydraulic or
diesel fuel component, hose or tube, turn engine OFF.
Wear heavy, protective gloves and eye protection.
NEVER check for leaks using any part of your body; use
a piece of cardboard or wood instead. If injured, seek
medical attention immediately. Diesel fuel leaking under
pressure can explode. Hydraulic fluid and diesel fuel
leaking under pressure can penetrate the skin, causing
infection, gangrene, and other serious personal injury.
Relieve all pressure before disconnecting any
component, part, line or hose. Slowly loosen parts and
allow release of residual pressure before removing any
part or component. Before starting engine or applying
pressure, use components, parts, hoses and pipes that
are in good condition, connected properly, and tightened
to the proper torque. Capture fluid in an appropriate
container and dispose of it in accordance with prevailing
environmental regulations.
PRESSURE TESTING: When conducting any test, only
use test equipment that is correctly calibrated and in good
condition. Use the correct equipment in the proper
manner, and make changes or repairs as indicated by the
test procedures to achieve the desired results.
LEAVING VEHICLE: Lower the attachment to the ground
before leaving the vehicle.
TIRE PRESSURE: Always keep tires inflated to the
proper pressure to help prevent dangerous travel and
load-handling situations. DO NOT over-inflate tires.
1.7 EMERGENCY EXIT REAR WINDOW
The rear window (1), used on the optional enclosed cab
only, can be used as an emergency exit by removing the
latch pin (2) located on the window latch (3). The window
is then free to swing open.
