Snorkel SR3370 - Manual (Page 53)

NOTE
When you release the Steering rocker-switch „
the steering wheels remain pointed in the
direction you left them. They do not return to
straight ahead the way automobile wheels do.
You will have to press the opposite side of the
Steering rocker-switch
„ to return to straight line
travel. In tight spots you should stop the SR, turn
the wheels the direction you want to go, then,
after you have aimed the steering wheels,
squeeze the Safety Control
ƒ and move the
Joystick Controller • slowly forward or backward.
q Raising the Platform
To raise the plat form from the plat form con trol box
do the fol low ing:
1. The engine must be running. If not, start it
from the platform control box as described
above.
Figure 8.19
2. Set the Lift/Drive Selector • (see Figure
8.19) to lift (left).
NOTE
If the Lift Indicator Light € is not lit, the platform
will not go up because: the chassis is not level,
the stabilisers are not properly set, or the
articulating axles are not set. Correct the problem
then continue.
NOTE
The platform is about to move. If you have to
make an emergency stop, release the Joystick
Controller
• and sharply strike the Emergency
Stop switch ‚ straight in.
To make a nor mal stop, slowly move the Joy stick
Con trol ler
• to its cen tered neu tral po si tion then re -
lease it.
3. Squeeze and hold the Safety Control ƒ
against the Joystick Controller • (see Figure
8.19).
4. Pull the Joystick Controller • backward to
raise the platform, or push it forward to lower
it. The further you pull the Joystick Controller
• backward, the faster the platform rises.
There is only one down speed.
n Stabilisers
NOTE:
Using the stabilisers.
The platform must be fully lowered to enable the
stabilisers to operate.
Once the platform is raised the stabilisers cannot
be set or adjusted.
Before operating the stabilisers check to see that
the ground conditions under the four stabiliser
pads is firm, stable and unobstructed.
If the platform is up and the ground compresses
unevenly under different stabiliser pads the SR
might fall over causing serious injury or death.
Check the level bubble frequently during
operation. If any movement of the bubble
occurs, immediately lower the platform and
readjust the stabilisers to re-center the bubble in
the ring.
When us ing the sta bi lis ers al ways check that all
four are firmly on the ground and that they are clear
of man hole cov ers, drains, etc., which may col -
lapse. If the ground is at all soft, steel plates at least
300mm x 300mm x 6mm should be placed un der
the feet to spread the weight.
Death or serious injury can result if an SR tips
over. Do not use the stabilisers to gain extra
working height, they are not designed for that
purpose. At least one of the stabilisers should
raise the SR above the ground - use the other
three to level the SR as necessary.
The SR will not DRIVE un less all four sta bi lis ers are
com pletely raised i.e. If any one of the sta bi lis ers is
even slightly low ered the DRIVE func tion is dis -
abled.
