er.
Start the engine and extend the warming-
up operation.

period.
(2) Inspect the radiator frequently, and keep cooling fins clean.
(3) Prevent sand or dust from getting into the fuel tank and the hydraulic tank during refilling.
(4) Prevent sand or dust from penetrating into the hydraulic circuit by tightly closing the breather
cap of the hydraulic oil tank. Replace the hydraulic oil filter frequently.
(5) Keep all lubricated parts, such as pins and bushings, clean at all times.
(6) If the air conditioner and heater filters clogged, the heating or cooling capacity will drop.
Clean or replace the filters more frequently.
3) SEASHORE OPERATION
(1) Prevent ingress of salt by securely tightening plugs, cocks and bolts of each part.
(2) Wash the machine after operation to remove salt residues.
Pay special attention to the electrical parts and the hydraulic cylinders to prevent corrosion.
(3) Inspection and lubrication must be carried out more frequently.
Supply sufficient grease to replace all old grease in bearings which have been submerged in
water for a long time.
