SECTION 8 - GENERAL SPECIFICATIONS & OPERATOR MAINTENANCE
Reservoir Filling :
i. Unscrew the filling cap and fill the tank with
new oil until the level (visible through the
filling hole or through the tank, depending on
the hydraulic unit installed) is 1 cm below the
filling hole.
j. Install the cap and perform several steering
movements to bleed the air from the hydraulic
circuit.
NOTE: Tighten the hydraulic lines as soon as the oil starts
flowing out.
k. Add oil in the tank if necessary.
9. Tires And Wheels
Tire wear and damage :
Inspect tires periodically for wear or damage. Tires with
worn edges or distorted profiles require replacement.
Tires with significant damage in the tread area or side
wall, require immediate evaluation before placing the
machine into service.
Wheel installation :
It is extremely important to apply and maintain proper
wheel mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN
STUDS AND POSSIBLE SEPARATION OF WHEEL FROM THE
AXLE. BE SURE THAT THE LUG NUTS ARE SEATED PROPERLY
TO THE WHEEL.
Use a torque wrench to tighten the fasteners. If you do
not have a torque wrench, tighten the fasteners with a
lug wrench, then immediately have a service garage or
dealer tighten the lug nuts to the proper torque. Over-
tightening will result in brea king the studs or
permanently deforming the mounting stud holes in the
wheels. The proper procedure for attaching wheels is
as follows :
• Start all nuts by hand to prevent cross threading.
DO NOT use a lubricant on threads or nuts.
• Tighten nuts in the following sequence :
Front
8-10
Front Wheels
• Tightening of the nuts should be done in stages.
Following the recommended sequence, tighten nuts
as follow :
Front
Rear
• Wheel nuts should be torqued after first 50 hours or
after each wheel removal. Check and torque every 3
months or 150 hours of operation.
TIGHTEN THE NUTS USING A TORQUE WRENCH. DO NOT USE
IMPACT WRENCH.
