Ether Start
Do not use ether or similar starting aids
in a Volvo or other engine with a pre-
heater. The Volvo engine is equipped
with a preheater. Introduction of ether or
other combustible material in the intake
manifold could cause a fire or explosion,
resulting in severe property damage, se-
vere personal injury or death.
Do not breathe the ether fumes. Breath-
ing ether fumes could result in personal
injury or death.
If using a cold start system, make sure
to read and follow the manufacturer’s in-
structions regarding its use, handling and
storage. Many starting fluids are sold in
capsules or pressure cans and improper
usage can be dangerous, resulting in ex-
plosion, personal injury or death.
Ether allows combustion with lower cylin-
der temperatures. A hand-held spray can for
injecting ether through the engine air intake
system will usually provide quick starting
to as low as –10
F (-23
C). Below this tem-
perature, a permanently installed system for
injecting a combustible vapor directly into
the intake manifold is necessary.
Only inject ether vapors when the engine is
cranking. Use it sparingly! Excessive ether
use can cause piston and ring damage.
