Driving Interlock Indicator Lamp Blinks or Glows, and the Lift Truck Stops Moving Mast Interlock Indicator Lamp Blinks or Glows,

◆ Care in Cold Weather

• Fuel Oils and Lubrication Oils

N00001

Use diesel fuel to fit the ambient temperatures. The cetane number should be 40 minimum. If you operate the lift truck where ambient temperatures are normally low, you may need fuel with a high cetane number.

CAUTION

– Cloud point must be 6°C (11°F) below the lowest ambient temperature. – Use engine oil and gear oil to fit the ambient temperature.

• Battery

Float Electrolyte level

Electrolyte

Glass tube

N00009

– Consult battery manufacturer for specific gravity for your specific battery. – When you park your lift truck overnight, leaving it outside a garage, remove the battery and keep it warm. – The electrolyte of a fully charged battery will not freeze to -35°C (-31°F).

CAUTION

– After distilled water has been added to the battery, run the engine for a while. This mixes the added water with the electrolyte and will reduce the risk of freezing and damaging the battery. – DO NOT attempt to restore a battery's charge by pouring boiling water over it. This could break the battery case, resulting in acid contact with skin or eyes.

• Engine Coolant

N00003

– Antifreeze used in the engine cooling system of a new lift truck shipped from the manufacturer provides sufficient freeze protection to -30°C (-22°F). – If ambient temperatures are below -30°C (-22°F), add antifreeze.

NOTICE:

For type and concentration of antifreeze, consult your authorized Cat lift truck dealer.

◆ Care in Hot Weather

• Fuel Oils and Lubrication Oils

N00004 Use fuel oil, engine oil and gear oil to fit the ambient temperatures.

NOTICE:

For selection of fuel oil, engine oil and gear oil, consult your authorized Cat lift truck dealer.

• Battery

In hot and/or dry weather, check the battery cells for proper electrolyte level more often than in cold weather. Add distilled water whenever the level is low.

• Engine Coolant

Be careful NOT to have scalding hot coolant or steam blow out of the reserve tank. Remove the radiator cap only after engine cools.

NOTICE:

Coolant evaporates rapidly and the engine is likely to get overheated when the lift truck is operated continuously or on a grade. During such an operation, observe the engine coolant temperature gauge for symptoms of overheating.

NOTICE:

If the engine coolant temperature gauge shows the red zone, see the topic, "Engine Coolant Temperature Gauge Shows Red Zone."

CAUTION

If the engine coolant temperature gauge shows the red zone, the engine may be overheated. ◆ Severe Dust or Lint Conditions

N00006

Check and service the air cleaner element more frequently.

Check the radiator core more frequently for clogging or trash build-up. Clean or wash the lift truck as needed.

Recommended Inspection Period Every 50 service hours or weekly, whichever comes first
