CAUTION :

CAUTION :

NEVER! use any other part of the roller for

lifting purposes. Use the lifting eye. Using other
parts of the roller for lifting will cause severe
damage to the roller,

Tipping (Rollovers)

NEVER! operate the roller on side slopes (Figure 5). The

possibility exist that the roller could tip over (roll over), thus
causing bodily harm even death and serious damage to the
equipment.

ONLY! use steel ropes or chains that are
capable of lifting at least 1,940 lbs. (880 kg ).

Figure 5. Recommended Slope

OPERATING ON SLOPES

Special care must be taken when operating the roller on hills or
slopes. There exist the possibility of serious injury to the operator
and severe damage to the roller in the event of a roll over.
ALWAYS operate the roller up and down hills rater than from
side to side. For safe operation hillside slopes should not exceed
12 degree (21 % grade). See Figure 4 below.

In the event the roller does tip over, extreme care must be taken
to prevent damage to the engine. When the roller has been
tipped over, oil from the engine crankcase can flow into the
combustion chamber, which can severely damage the engine
the next time it is started.

IMMEDIATELY after a unit has tipped over upright the unit as
soon as possible to prevent oil from leaking into the combustion
chamber.

CAUTION :
