Maintenance Checks and Lubrication
The following are the recommended maintenance instructions for the Load King Boom Truck. The
outrigger hinge points do not require lubrication either. The MASTER LUBE CHART above shows the
proper lubricants to use and the frequency of lubrication.
DAILY OPERATOR CHECKS
A regular schedule of maintenance is essential to keep your unit at peak operating efficiency. Operators
responsible for the care of the unit should be familiar with the daily and weekly maintenance schedules
and what to look for. Below are the items to check to ensure the unit is in proper and safe operating
condition, and recommended intervals of care.
CHECKING THE TRUCK
Proper operation of the crane is dependent on the condition of the truck, so the following checks should
be done daily:
1. Set parking brake, start engine, put transmission in neutral and engage PTO. Allow the hydraulic
system to warm up slightly. Check for any sign of oil leaks or damaged hoses.
2. Extend all four outriggers to a firm surface, raise truck to just clear tires from ground, and shut the
engine off. This is an opportunity to ensure the outrigger holding cartridges are not leaking under
load.
3. Check the lights for proper operation.
4. Check engine fluids. Maintain oil and water levels above the add mark.
Do additional checks per truck operator’s manual.
DAILY CHECKS
Before daily operation begins, the crane should be run and checked for the following:
1. Set parking brake, start engine, put transmission in neutral and engage PTO. Allow the hydraulic
system to warm up slightly. Check for any sign of oil leaks or damaged hoses.
2. Extend all four outriggers to a firm surface, raise truck to just clear tires from ground, and shut the
engine off. This is an opportunity to ensure the outrigger holding cartridges are not leaking under
load.
3. Check all controls for any signs of sticking and proper operation of functions. With boom elevated
and extended, shut off engine and check for signs of boom drift.
4. Check to make certain that the load line is properly spooled on the winch drum and that it is not
damaged.
5. Check all Operator Aids for proper operation (ATB, Rated Capacity Indicator System and Holding
Valves).
6. Do daily lubrication.
7. Check that the downhaul weight (load block or ball) is properly secured to the loadline and the hook
safety latch is in proper operating condition.
