WARNING
Raise the hood to the highest
point, then slowly lower the
hood until the prop locks up.
Inspect condition of support
and brackets. After raising
the hood, insert the s-
shaped hook through the
two matching holes in the
prop channel to prevent the
hood from accidently falling.
Reverse this procedure to
lower the hood.
If engine has been running,
let radiator cool before re-
moving cap. Remove cap in
two steps. First, place a
thick cloth over the cap and
slowly rotate cap to its first
stop, pause and let pressure
escape from cooling system.
Then rotate cap further until
you can remove it. Failure to
follow this procedure can re-
sult in serious burns.
Check coolant level in radiator
sight glass. If level is low, add a
mixture of antifreeze and clean
water to bring coolant to proper
level (check with organiza-
tional maintenance for the
proper mixture).
