CAUTION

Not installing the tool as shown

will change the torque applied to the screw.
Proper torque and tightening sequence are
important.

Recommended Engine Oil

Use

XPS 4-STROKE SYNTH. BLEND OIL (SUMMER)

(P/N 293 600 121)

.

If the recommended XPS

TM

engine oil is not avail-

able, use a 10W40

mineral

engine oil compatible

with wet clutches.

NOTE:

The XPS engine oil has been thoroughly

tested to be free of any additives that could impair
the functionality of the supercharger clutch.

NOTICE

NEVER use synthetic oil. This would

impair the proper operation of the super-
charger clutch. Do not add any additives to
the recommended oil. Mineral oils not recom-
mended by BRP may also contain additives
(friction modifiers) that may cause inappropri-
ate slippage of the supercharger and eventu-
ally lead to premature wear. For this reason,
XPS Synthetic Blend Summer Grade oil or a
BRP approved equivalent are the only recom-
mended oils. Use of any oil not recommended
by BRP may void BRP's limited warranty.
