Cold Weather Starting Guidelines

A - Minimum Cranking RPM

B - No Aids

C - Electric Air Heat

D - Block Heat

E - Ether (See Caution)

F - Electric Air Heat and Block Heat

G - Ether and Block Heat (See Caution)

DO NOT use starting fluid near fire, sparks, or flames. DO NOT incinerate or puncture a starting fluid container.

Engines may be equipped with a block heater, air intake heater, coolant heater or fuel heater as cold weather starting aids. Your engines may be equipped with glow plugs as an automatic cold weather starting aid (see steps 1-4 following).

Starting aids are required below 0°C (32°F). They will enhance starting performance above these temperatures and may be needed to start applications that have high parasitic loads during cranking and/or start acceleration to idle.

Using correct grade of oil (per engine and machine operator's manual) is critical to achieving adequate cold weather cranking speed.

Synthetic oils have improved flow at low temperatures, especially in arctic conditions.

If air temperature is below -10°C (14°F), use an engine block heater.

Other cold weather starting aids are required at temperatures below -25°C (-13°F) or at altitudes above 1500 m (5000 ft). (See “Using a Booster Battery or Charger” later in this section.)

   Activating Glow Plugs (if applicable) with Key Start Switch

   A - Key Start Switch

   Follow steps 1—4 as listed under STARTING THE ENGINE, earlier in this section, then proceed as follows according to the instrument (gauge) panel on your engine.

   NOTE: Glow plugs operate automatically through the ECU. The Engine Preheater Indicator light (B) on these engines, should always illuminate when the switch is turned ON. In warm weather, the light illuminates briefly as a light check. In cold weather, the light remains on during the automatic operation of the glow plugs. Operating time depends on temperature. Do not crank engine until light turns off.

2. Turn key start switch (A) ON to activate glow plugs, but DO NOT crank engine until Engine Preheater Indicator light (B) turns off.

3. Follow remaining steps 5—7 as listed earlier in “Starting Engine” section.
