• Dirt, oil and fuel in the engine compartment near its hot parts may damage the machine and even cause
fires.
Check frequently and eliminate any leakage; if leakages occur repeatedly, contact your Komatsu Utility
Dealer.
Before starting the engine, check around and under the machine to verify:
1 - if there are loose screws or nuts;
2 - if there are oil, fuel or coolant leakages;
3 - the wear of the work equipment;
4 - the fastening of the electrical connections;
5 - the fastening of the engine exhaust pipe and manifold;
6 - the track tension and the fastening of the sprockets;
7 - if the safety and warning plates are sufficiently clean;
8 - if the handles of the operator’s cab are clean.
Any leak or anomaly must immediately be repaired/eliminated and any trace of oil or grease must be removed.
Further visual checks concern:
9 - the condition of the safety belt;
10 - the efficiency of the instruments and of the dashboard;
11 - the condition of the cab windows and the efficiency of the working lights.
• Do not smoke while refuelling or topping up the oils and do not use naked flames or non-homologated
lighting means to check the fuel and oil levels, in order not to cause fires.
• If fuel, oil, or lubricant are spilled while filling the tanks, clean the dirty areas immediately.
Before starting any operation, check the engine coolant, engine oil and hydraulic circuit oil levels.
At the end of work, provide for refuelling, in order to avoid the formation of condensate, always checking the fuel
level on the indicator provided on the dashboard.
• Avoid filling the tank completely, in order to leave room for the gas oil to expand.
• After refuelling, put back the fillercap, making sure that the bleed hole is completely open.
• Check the engine oil level with the machine in horizontal position and the hydraulic circuit oil level with
the arm and bucket cylinders retracted and the bucket teeth on the ground.
