COMPRESSION TEST
NOTE: This Polaris 4-Stroke engineis equippedwith
an automatic decompressor. Compression readings
will vary in proportion to cranking speed during the
test. Average compression (measured) is about
70--90 psi
during a compression test.
Smooth idle generally indicates good compression.
Low engine compression is rarely a factor in running
condition problems above idle speed. Abnormally
high compression can be caused by a decompressor
malfunction, or wornor damaged exhaust camlobes.
Inspect camshaft and automatic decompression
mechanism if compression is abnormally high.
A cylinder leakage test is the bestindicationof engine
condition on models with automatic decompression.
Follow tester manufacturer’s instructions to perform
a cylinder leakage test. (Never use high pressure
leakage tester as crankshaft seals may dislodge and
leak).

Standard70--90 PSI
Cylinder Leakage
Service Limit: 10 %
(Inspect for cause if leakage exceeds 10%)
ENGINE MOUNTS
Inspect rubber engine mounts for cracks or damage.
ENGINE FASTENER TORQUE
Check engine fasteners and ensure they are tight.

SEALED LOW MAINTENANCE
BATTER
Y
NOTE: All Low Maintenance batteries are fully
charged and tested at the factory before
installation. Expected shelf life varies on storage
conditions. As a general rule before placing the
battery into service, check the battery condition
and charge accordingly.
Battery Check:
1. Check the date label on the side of the battery to
calculate when to check voltage. The battery
should be checked every 3 months.
2. Check the voltage with a voltmeter or multimeter.
A fully charged battery should be 12.8 V
or
higher
.
3. Ifthe voltageisbelow12.8V, thebattery willneed
to be recharged.
