Snorkel TB37 2001 - Manual (Page 39)

Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of
10°F (0°C) or below.
Preparing for Operation
Use the following procedure to prepare the aerial plat-
form for operation.
1. Perform a prestart inspection as described in
Chapter 7.
2. Place the battery disconnect switch in the on posi-
tion.
3. Close and latch the doors.
4. Before painting or sandblasting make sure the
sandblast protection kit and the platform control
cover are properly installed. These options, when
used properly will protect the control placards and
cylinder rods from paint overspray and abrasion
while sandblasting.
Lower Controls
The lower controls override the upper controls. This
means that the lower controls can always be used to op-
erate the platform regardless of the position of the up-
per control emergency stop button.
Boom, turntable, and platform functions may be oper-
ated from the lower controls. The lower controls may be
used for initial set up of the aerial platform and raising
and lowering the platform while testing or inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls.
1. On dual fuel machines, set the fuel switch to either
LPG or gasoline.
2. Open the shut-off valve on the tank if using LPG.
3. Place the emergency stop switch (refer to Figure
8.2) in the on position and place the controls switch
in the ground position.
