With the Bombardier-Rotax high per-
formance engine, a break-in period of
6 to 10 operating hours is required be-
fore running the vehicle at full throttle.
During this period, brief full throttle
accelerations
and
constant
speed
variation will contribute to a good
break-in. Continued wide open throttle
accelerations can be detrimental. Never
let your engine overheat.
_
CAUTION: Incorrect or lack of
break-in period will result in en-
gine horsepower loss.
Oil must be added to the gasoline in
pre-measured amounts then both' oil
and gasoline should be thoroughly
mixed together before fueling the tank.
The correct gasoline is premium gaso-
line, (not less than 98 octane) available
from all service stations.
_
CAUTION: Never experiment
with different fuel or fuel ratios.
Never use low lead or non leaded gaso-
line, naphtha, methanol or simular
products.
Use a 20 / 1 ratio castor base snow-
mobile oil, this type of oil is specially
formulated to meet the lubrication re-
quirement of the high performance
Bombardier-Rotax engine.
_
CAUTION: Use of outboard or
other than recommended oil can
result in engine damage.
The importance of using the correct
fuel mixture cannot be overstressed.
An incorrect fuel ratio results in a se-
rious engine damage.
Recommended fuel/oil ratio is 20/ 1.
5 gallons of premium gasoline plus 1
can of 20/ 1 castor base snowmobile
oil
=
