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.
