INSTALLING THE SILENCER AND
EXHAUST PIPE
1. Install:
• Gasket
• Exhaust pipe "1"
• Nut (exhaust pipe) "2"
First, temporarily install both nuts, then tighten
either of these nuts to 13 Nm (1.3 m•kg, 9.4
ft•lb) and the other to 20 Nm (2.0 m•kg, 14 ft•lb),
and then come back to the first one and retight-
en it to 20 Nm (2.0 m•kg, 14 ft•lb).
2. Install:
• Silencer clamp "1"
• Gasket "2"
• Silencer "3"
• Washer "4"
• Bolt (silencer) "5"
CHECKING THE COOLANT LEVEL
Do not remove the radiator cap "1", drain
bolt and hoses when the engine and radia-
tor are hot. Scalding hot fluid and steam
may be blown out under pressure, which
could cause serious injury. When the en-
gine has cooled, place a thick towel over the
radiator cap, slowly rotate the cap counter-
clockwise to the detent. This procedure al-
lows any residual pressure to escape. When
the hissing sound has stopped, press down
on the cap while turning counterclockwise
and remove it.
Hard water or salt water is harmful to the en-
gine parts. You may use distilled water, if
you can't get soft water.
1. Place the machine on a level place, and hold
it in an upright position.
2. Remove:
• Radiator cap
3. Check:
• Coolant level "a"
Coolant level low
→
Add coolant.
