CHAPTER 4
OPERATION
Before starting the engine and operating the
loader, review and comply with all safety rec-
ommendations in the Safety chapter of this manual. Know how to
stop the loader before starting it. Also, be sure to fasten and prop-
erly adjust the seatbelt(s) and lower the operator restraint bar.
Before Starting the Engine
Before starting the engine and running the loader, refer to the Controls and Safety
Equipment chapter and become familiar with the various operating controls, indi-
cators and safety devices on the loader.
Fuel
Use only ultra-low sulfur diesel fuel to maintain proper engine performance. Use
of diesel fuel with more than 15 ppm of sulfur can potentially damage the engine.
BioDiesel mixtures of up to a 5% (B5) are acceptable. Ultra-Low Sulfur Diesel
(ULSD) fuel lubricity must have a maximum scar diameter of 0.45 mm, as mea-
sured by ASTM D6079 or ISO 12156-1, or a minimum of 3100 grams, as mea-
sured by ASTM D6078. Contact your fuel supplier for details.
Static electricity can produce dangerous sparks at the fuel-filling nozzle. Do not
wear polyester, or polyester-blend clothing while fueling. Before fueling, touch
the metal surface of the machine away from the fuel fill to dissipate any built-up
static electricity. Do not re-enter the machine but stay near the fuel filling point
during refueling to minimize the build-up of static electricity. Do not use cell
phones while fueling. Make sure the static line is connected from the machine to
the fuel truck before fueling begins.
Ultra-Low Sulfur Diesel (ULSD) poses a greater static ignition hazard than earlier
diesel formulations. Avoid death or serious injury from fire or explosion; consult
with your fuel or fuel system supplier to ensure the entire fuel delivery system is
in compliance with fueling standards for proper grounding and bonding practices.
Starting the Engine
The following procedure is recommended for starting the engine:
1. Carefully step up onto the back of the bucket or attachment and grasp the
handholds to enter the operator’s compartment.
2. Close the door, fasten the seatbelt(s) and lower the restraint bar.
3. Verify the following:

the lift/tilt, drive and auxiliary hydraulic controls are in their neutral
positions,

the parking brake switch is ON.
Note: When the key is turned to the RUN position, an indicator lamp will light on
the instrument panel and a buzzer will sound momentarily to remind users to
fasten the seatbelt.
