Getting ready to ride
Perform the Pre-Operation Checks on page
5-1. Follow the instructions starting on page
6-2 to start the engine. Turning
Use care in turns – turning the steering wheel
too far or too fast can result in loss of control
or a rollover. Slow down before entering turns.
When making tight turns from a standstill or at
slow speeds, avoid sudden or hard accelera-
tion. Driving aggressively or making abrupt
maneuvers even on flat, open areas can
cause side rollovers. Avoid sideways sliding,
skidding, or back-wheel sliding, and never do
donuts. If you feel the Viking begin to slide
sideways or the back wheels slide during a
turn, steer into the direction of the slide, if pos-
sible, and gradually let off the accelerator ped-
al to regain directional control and avoid
rollover. For example, if you feel the back of
the vehicle start to slide to your right, steer to
the right.1XP7C_EE.book Page 16 Monday, June 9, 2014 5:17 PM

Uphill
Do not attempt to climb hills until you have
mastered basic maneuvers on flat ground.
Drive straight up hills, and avoid crossing the
side of a hill, which increases your risk of roll-
over. Practice first on gentle slopes before at-
tempting steeper hills. Always check the
terrain carefully before attempting any hill.
To climb a hill, you need traction, momentum,
and steady throttle. For more traction and
control for climbing steeper and/or rougher
slopes, shift into low gear and select “4WD” or
“DIFF LOCK”. Travel fast enough to maintain
momentum, but not so fast that you cannot re-
act to changes in the terrain as you climb. Slow down when you reach the crest of the hill
if you cannot see clearly what is on the other
side – there could be another person, an ob-
stacle, or a sharp drop-off.
If you start to lose traction or momentum
when climbing, and decide you will be unable
to continue, use the brakes to stop. Do not at-
tempt to turn the vehicle around. With your
foot on the brake pedal, look behind you and
plan your descent. Shift the drive select lever
into reverse so you can use engine braking to
slow your descent. Release the brake and be-
gin to coast down the hill. Use engine braking
as much as possible, gently applying the
brakes when necessary.1XP7C_EE.book Page 22 Monday, June 9, 2014 5:17 PM

Downhill
Check the terrain carefully before going
downhill. When possible, choose a path that
lets you drive your vehicle straight downhill.
Choose your path carefully and drive slowly
enough to be able to react to obstacles that
you encounter.
For more traction and control, before going
down steeper and/or rougher slopes, shift into
low gear and select “4WD” or “DIFF LOCK”.
Engine braking will help you go downhill slow-
ly. Go as slowly as possible. If you begin to go
too fast, apply the brakes gently. Avoid hard
application of the brakes, which could cause
the vehicle to slide.If you are sliding or skidding, try to steer in the
direction the vehicle is sliding, to regain con-
trol. For example, if you feel the back of the
vehicle start to slide to your right, steer to the
right.
If you must turn on the hill to avoid an obsta-
cle, do so slowly and carefully. If the vehicle
starts to tip, immediately steer in the downhill
direction if there are no obstacles in your path.
As you regain proper balance, gradually steer
again in the direction you want to go.1XP7C_EE.book Page 23 Monday, June 9, 2014 5:17 PM

Brush or wooded areas
When operating in areas with brush or trees,
watch carefully on both sides and above the
vehicle for obstacles such as branches that
the vehicle might hit, causing an accident.
Watch for brush that might enter the vehicle
as you pass and strike you or the passengers.
Never hold onto the cage/frame. The passen-
gers should always hold onto the passenger
handhold with both hands.
The muffler and other engine parts become
extremely hot during operation and remain
hot after the engine has stopped. To reduce
the risk of fire during operation or after leaving
the vehicle, do not let brush, grass and other
materials collect under the vehicle, near the
muffler or exhaust pipe, or next to other hot
parts. Check under the vehicle after operating
in areas where combustible materials may
have collected. Do not idle or park the vehicle
in long dry grass or other dry ground cover. Encountering obstacles
If you cannot go around an obstacle, such as
a fallen tree or a ditch, stop the vehicle where
it is safe to do so. Set the parking brake and
get out to inspect the area thoroughly. Look
from both your approach side and exit side. If
you believe you can continue safely, choose
the path that will allow you to get over the ob-
stacle and at as close to a right angle as pos-
sible to minimize vehicle tipping. Go only fast
enough to maintain your momentum but still
give yourself plenty of time to react to chang-
es in conditions.
If there is any question about your ability to
maneuver safely over the obstacle, you
should turn around if the ground is flat and you
have the room or back up until you find a less
difficult path.1XP7C_EE.book Page 26 Monday, June 9, 2014 5:17 PM

5B410012Engine oil and oil filter cartridgeCheck engine oil level before each operation.
In addition, change the oil and the oil filter car-
tridge at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level1. Park the vehicle on a level surface.
2. Check the engine oil level on a cold en- gine. TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading.3. Lift the cargo bed up. (See page 4-27 forcargo bed lifting and lowering proce-
dures.)
4. Remove the engine oil dipstick, and then wipe it off with a clean rag.

check the oil level. TIPThe engine oil should be between the mini-
mum and maximum level marks.1. Maximum level mark 2. Minimum level mark

6. If the engine oil is at or below the mini- mum level mark, remove the right rear
panel by removing the quick fastener
screws and bolts, and then add sufficient
oil of the recommended type to raise it to
the correct level.1. Right rear panel 2. Quick fastener screw (× 4)

NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. Do not use oils with
a diesel specification of “CD” or oils
of a higher quality than specified. In
addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
12. Start the engine, and then let it idle for several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
13. Turn the engine off, wait at least 10 min- utes, and then check the oil level and cor-
rect it if necessary.
14. Install the right rear panel by installing the bolts and the quick fastener screws. 15. Lower the cargo bed.1XP7C_EE.book Page 14 Monday, June 9, 2014 5:17 PM

5B410015CoolantThe coolant level should be checked before
each ride.
Checking the coolant level 1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture. TIPThe coolant should be between the minimum
and maximum level marks.
1. Coolant reservoir cap
2. Maximum level mark 3. Minimum level mark3. If the coolant is at or below the minimum level mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap.
Coolant reservoir capacity
(up to the maximum level mark): 0.28 L (0.30 US qt, 0.25 Imp.qt)
