Never operate the ATV on hills too steep for the
ATV or for your abilities. Practice on smaller
hills before attempting larger hills.


Always follow proper procedures for climbing
hills as described in this manual. Check the ter-
rain carefully before you start up any hill. Never
climb hills with excessively slippery or loose
surfaces. Shift your weight forward. Never
open the throttle suddenly. Never go over the
top of a hill at high speed.


Always follow proper procedures for going
down hills and for braking on hills as described
in this manual. Check the terrain carefully be-
fore you start down any hill. Shift your weight
backward. Never go down a hill at high speed.
Avoid going down a hill at an angle that would
cause the vehicle to lean sharply to one side.
Go straight down the hill where possible.

Always follow proper procedures for crossing
the side of a hill as described in this manual.
Avoid hills with excessively slippery or loose
surfaces. Shift your weight to the uphill side of
the ATV. Never attempt to turn the ATV around
on any hill until you have mastered the turning
technique described in this manual on level
ground. Avoid crossing the side of a steep hill if
possible.


Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
ing, use proper gear range and maintain a
steady speed when climbing a hill. If you stall or
roll backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, follow-
ing the procedure described in this manual.

Loading
Cargo or a trailer can change the stability and han-
dling of an ATV. You must use common sense and
good judgment when carrying cargo or towing a
trailer. Keep the following points in mind:

Never exceed the weight limits shown. An
overloaded ATV can be unstable.
MAXIMUM LOADING LIMIT

Vehicle loading limit (total weight of cargo,
rider and accessories, and tongue weight):
220 kg

Front carrier: 45 kg

Rear carrier: 85 kg

Storage box: 2.0 kg

Trailer hitch:
Pulling load (total weight of trailer and car-
go): 550 kgf
Tongue weight (vertical weight on trailer
hitch point): 15 kgf
U5KM60.book Page 27 Thursday, June 21, 2001 2:40 PM

6-29

Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad-
just the load in the trailer, if necessary, to re-
duce the weight on hitch. If you are carrying
cargo and towing a trailer, include the tongue
weight in the maximum vehicle load limit.

Load cargo on the carrier as close to the center
of the vehicle as possible. Put cargo at the front
of the rear carrier. Center the load from side to
side.

Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.

Make sure the load does not interfere with con-
trols or your ability to see where you are going.
U5KM60.book Page 29 Thursday, June 21, 2001 2:40 PM

6-31

Ride more slowly than you would without a
load. The more weight you carry, the slower
you should go. Although conditions vary, it is
good practice not to exceed low range whenev-
er you are carrying heavier loads or when tow-
ing a trailer.

Allow more braking distance. A heavier vehicle
takes longer to stop.

Avoid making sharp turns unless at very slow
speeds.

Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.
WARNING
Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
vehicle handling which could lead to an acci-
dent. Cargo should be properly distributed and
securely attached. Reduce speed when carry-
ing cargo or pulling a trailer. Allow greater dis-
tance for braking.

7-41 1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie exterior.
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As
you do so, put your weight on the footboard to the
outside of the turn (opposite your desired direc-
tion) and lean your upper body into the turn. Use
the throttle to maintain an even speed through the
turn. This maneuver will let the wheel on the inside
of the turn slip slightly, allowing the ATV to make
the turn properly.
This procedure should be practiced at slow speed
many times in a large off-road area with no obsta-
cles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
turn, come to a stop and then practice the proce-
dure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the
front wheels by moving forward on the seat.
Once you have learned this technique you should
be able to perform it at higher speeds or in tighter
curves.

CLIMBING UPHILL
Use proper riding techniques to avoid vehicle
overturns on hills. Be sure that you can maneuver
your ATV well on flat ground before attempting any
incline and then practice riding first on gentle
slopes. Try more difficult climbs only after you
have developed your skill. In all cases avoid in-
clines with slippery or loose surfaces, or obstacles
that might cause you to lose control.
WARNING
_ Never operate the ATV on hills too steep for
the ATV or for your abilities. The vehicle can
overturn more easily on extremely steep hills
than on level surfaces or small hills. Practice
on smaller hills before attempting large hills. _It is important when climbing a hill to make sure
that your weight is transferred forward on the ATV.
This can be accomplished by leaning forward and,
on steeper inclines, standing on the footboards
and leaning forward over the handlebars.
