FUEL Engine fuel and propane/diesel for the upper unit heater should be adequate for
sustained operations.
LUBRICATION Perform the daily lubrication as required in the Lubrication Recommendations.
HYDRAULIC SYSTEM Check hoses, tubes, components, reservoir sight gauge, valves,
pumps, motors, connections, reservoir oil temperature, cylinder mounting bushings and pins.
LINES AND BLOCKS Inspect the hoist lines, hoist block, hook latch, and ball hook, as well
as the crane attachment in general for readiness.
TIRES The tires should be checked for proper pressure before traveling the machine. The
tires should only be checked when cold. Refer to the Tire Pressure Chart on the Load
Rating Chart.
WHEEL NUTS Torque wheel nuts to 400-500 Ft.Lbs. Tighten daily during the first 50 miles
of service on new units and any time the wheels have been removed. Tighten nuts
alternately around the wheel.
GENERAL CONDITION Inspect the machine in general for wear, leakage and damage.
AIR TANKS Open the air tank drain cocks to blow out moisture and sediment.
TRANSMISSION OIL Check the transmission oil level. If oil is 2-3 inches above the full mark
there is enough to start the engine. After the engine has been started and the transmission
warmed to 180-200° F allow the engine to idle and ensure that the fluid level is between the
“full” and “add” marks.
FUEL FILTER Water should be drained from the fuel/ water separator on a Daily Basis. The
fuel/water separator and fuel filters have drain cocks located at the bottom. Filter is located
in the engine compartment on the left rear of the machine. For further information, See
Section 9, “Engine Maintenance Checks”.
EMERGENCY STOP The emergency stop button is located on the lower part of the dash to
the left of the steering column in the operator’s cab. In an emergency, this button can be
pushed in to stop all crane functions including engine operation. You must pull the button
out before you can resume normal operation of the crane.
SAFETY EQUIPMENT Check the safety equipment, including all lights, brakes and hazard
warning devices.
CHROMED CYLINDER RODS Periodically, (at least once a month or more often if
subjected to damp or corrosive atmosphere), wipe down exposed chrome rod surface with
a good rust-proofing agent or lubricant. Recommended using "CROWN FORMULA 101".
