Cold Weather Starting Guidelines
CAUTION: DO NOT use starting fluid on
engines equipped with air intake heaters or
glow plugs. Ether injector starting fluid is highly
flammable and may explode, causing serious
injury.
DO NOT use starting fluid near fire, sparks, or
flames. DO NOT incinerate or puncture a
starting fluid container.
Engines may be equipped with intake air heaters, coolant
heaters, fuel heaters, or ether injectors as cold weather
starting aids. Later “475” 4-valve cylinder head engines
are equipped with glow plugs as an automatic cold
weather starting aid.
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.
Other cold weather starting aids are required at
temperatures below -30
°
C (-22
°
F) or at altitudes above
1500 m (5000 ft). (See “Using a Booster Battery or
Charger” later in this section.)
1. 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.
2. 275-Series Engines Without Air Intake Heaters:
Manually activate ether injectors.
