Snorkel MB20N-sn0001-0131 - Manual (Page 13)

Operation
MB20N/MB26
Travel with platform elevated ONLY on firm and level
surfaces.
NOTE:
The Work Platform will travel at reduced speed when in
the elevated position.
Before operating the MB20 Work Platform it is
imperative that the pre-operation Safety Inspec-
tion has been completed and any deficiencies
have been corrected. The operator must also be
fully trained in the use of this machine.
Before beginning any operation, the following checks
should be carried out.
NOTE: Chassis controls are for service use only. Do
not leave a second ( spare) key in the Lower Con-
sole. Use of a single key ensures full machine con-
trol by the person in the platform.
1. Enter the Platform through the entrance at the
rear of the MB20/26 and ensure that the drop bar
is in position. Raise and lock the entry step by
means of the pedal in the platform.
2. Before using the machine all local Safety
Regulations involving helmets and restraining
devices should be observed. Safety harness
lanyards, not exceeding 1 metre in length,
should be attached to anchor points in cage floor.
3. Ensure that the ‘ON/OFF/OVERRIDE’ switch on
the Upper Control Box is turned to the ‘ON’
position and both emergency stop buttons are off
(twist clockwise if necesary).
4. Check the green battery indicator band L.E.D. is
illuminated. If not, the battery may need recharg
ing.
5. Check if the audible alarm sounds due to unlevel
ground. None of the functions can work if the
machine is not level.
1. Verify that both Lower and Upper Control
Console Emergency Stop Button is in
the ‘ON’ position (turn clockwise to reset).
2. Climb into the Platform and check that
the Keyswitch is turned to the ‘ON’ position and
that the Drive/Lift Selector switch is positioned at
DRIVE FUNCTION. Ensure that the drop bar is
in position.
3. Check that the route is clear of persons,
obstructions, pot holes or ledges and is capable
of supporting the wheel loads. Also, check that
the clearances above, below, and to the side of
the Work Platform are sufficient.
4. To steer the MB20/26, activate the Deadman
Switch while pushing the ‘Rocker’ Thumb-
Switch, on top of the Joystick, LEFT or RIGHT
to turn the wheels. Observe the tires while
manoeuvring to ensure proper direction.
NOTE:
Steering is not self-centering. The
wheels must be returned to the straight ahead
position by operating the Steering Switch.
