AFTER STARTING ENGINE
Whenever a machine has been parked for a long period
of time, some of the systems will cool to below normal
operating temperatures. Always warm the machine
systems before operating the machine at full operation
Damage to engine valve control components can result
from engine operation for short intervals during operation
in very cold weather conditions. If the engine is not
allowed to warm completely, the engine can be damaged
by repeated starting and stopping.
To avoid damage, always run the engine until the coolant
temperature is at least 180°F (82°C).
After the engine is warm, warm up the other systems.
Start with the hydraulics. Run the engine at less than
one-third throttle, and slowly move the control lever to
lift the attachment. Initially, lift the control lever for a
few inches (centimeters). Lower the attachment slowly.
Continue the sequence: raising, lowering, extending, and
retracting. Extend the travel during each cycle. Perform
this operation for all hydraulic circuits. Alternate between
all of the attachments.
Exercise the transmission and the power train. If you
cannot move the control for the transmission, perform
the following steps:
•
Engage the parking brake or apply the brake pedal.
•
Run the engine slightly above LOW IDLE.
• Shift the transmission several times from
FORWARD to REVERSE.
Release the brake. Move the equipment forward
and backward for several feet (meters). Exercise the
machine for several minutes.
To reduce the total warm up time, start exercising the
entire machine before you complete the hydraulic warm
up time.
Operate under light load until the systems reach normal
operating temperatures.
If the engine temperature is not high enough enclose the
engine and block the radiator. A thermostat that opens
at a higher temperature will not increase the engine
temperature if the engine is not under load.
To prevent seal damage and gasket damage, keep the
engine crankcase breather pipe clear of blockage.
In extreme conditions, use a canvas over the engine
compartment. Heat the engine area with a space
heater. This will aid in starting the engine. Extending the
canvas over the hydraulic components will provide initial
warming of the components.
Multigrade lubricants (10W30) may be used successfully
at ambient temperatures below the pour point of the
oil. However, in order to use this oil, you must leave the
engine running at low idle. This helps keep lubricants
and compartments warm for the engine and for the
transmission. Running the engine at low idle will not
keep the hydraulic systems warm.
SAFETY LINK
The chassis for the MSV articulates or pivots in the
middle. This is used to help maneuver the MSV and
provides a smaller turning radius.
During maintenance it is advisable to lock-out the
articulation of the chassis.
To lock the Chassis:
1. Pull straight ahead to align the chassis.
2.
Locate the safety link on the frame behind the cab
(Figure 37 Safety Link Open).
3. Pull out the removable pin (Figure 38).
4. Swing the link to meet the back half and insert the
pin.
When the safety link is not in use, it should be stored
against the front frame.
