Yale GDP040-070VX, Operating Manual

Page: 78 / 204

Before anyone is allowed in the platform, lift and lower
the mast slowly with the platform in place to make sure
the mast functions properly. Apply the parking brake. Do
not travel with people in the platform. The operator must
remain at the controls. Watch for overhead obstructions.
2. NO RIDERS. A lift truck is built for only
one person – the operator. It is dangerous
for anyone to ride on the forks or anywhere
else on the lift truck.
3. ADJUST SEAT - INTERNAL SUSPENSION.
Seat Position Adjustment (Swivel Seat)
• The seat swivels 10.5 degrees to the right to allow the
operator a more ergonomic position when driving in
reverse.
• The seat swivels 5 degrees to the left to allow an easier
exit of the truck.
• The neutral position is shown in Figure 11.
Seat Adjustment for Operator Weight
CAUTION
A major cause for high Whole Body Vibration is caused
by the operator not adjusting the seat to his/her weight.
NOTE: It is important to adjust the weight setting for each
operator.
NOTE: The seat is designed for a maximum weight of 135 kg
(298 lb).
• The target is for the "ride indicator" to fall between the
arrows when the operator sits upright in the seat with the
feet positioned on the pedals. This ensures that the oper-
ator is set at the midpoint of the 40 mm (1.57 in.) suspen-
sion.
• The weight adjustment knob can be turned left or right to
increase or decrease the weight resistance. As the weight
adjustment knob is turned the "stiffness" of the suspension
can be felt to increase or decrease depending on which
way the weight adjustment knob is turned.
