DESCRIPTION OF EQUIPMENT
The SNORKEL TL49J is of the parallel linkage vertical boom design, mounted on a road
towable trailer. The unique, yet very simple boom conguration gives the maximum safety and
control ability combined with a robust construction to withstand a heavy working environment
The TL49J machine is designed for two man capacity (200 kg S.W.L.).
The machine incorporates a bottom boom with tie-rod, a short vertical boom and a top boom
with a telescope section. The TL49J also has an independent hydraulically operated ick-out
boom and rotating cage for extra manoeuvrability.
The hydraulic system is of a failsafe design throughout, with built in hydraulic lock valves on
all of the rams as a precaution against hose failure. The machine is controlled by means of
proportional manual controls of the ‘direct hand’ lever operating type. These valves are located
at both the base and in the cage, as standard.
Electrically operated emergency lowering valves are tted as standard to allow the machine to
be lowered from the base and basket.
The hydraulically operated outriggers are tted with load sensing interlocks, to prevent the booms
from being raised without the outriggers being extended and under load. An interlock prevents
the hydraulic outriggers being accidentally retracted while the booms are raised. A simple
system of warning lights show the power supply is on and each of the outriggers is under load.

WARNING NOTICES
8. DO NOT operate the machine unless all four outriggers are down and in full contact
with the ground. The machine must be level and the wheels lifted visibly clear of the
surface before the booms are raised.
9. DO NOT move the machine with the
basket raised and never allow cage
or booms to slew into the path of
oncoming vehicles.
10. DO NOT operate the machine if the wind speed exceeds 12.5 m/s. Be aware that, when
working near high buildings or structures, shielding and funnelling effects may cause high
wind forces on days when the nominal wind speed in the open is low. Wind speed can
either be measured from the work platform with a hand held anemometer or estimated
using the Beaufort Scale.
BEAUFORT WIND SPEED SCALE
The Beaufort Scale of wind force is accepted internationally and is used in communicating
weather conditions. It consists of numbers 0 - 12, each representing a certain strength of
velocity of wind at 10m (33ft.) above ground in the open.
Approximate corrections for wind speeds at other heights are:
□ 2m subtract 30%;
□ 3m subtract 20%;
□ 6m subtract 10%
□ 15m add 10%;
□ 30m add 25%

4. Emergency Procedure, Manual Raising of Outriggers.
In the event of power failure, the outriggers can be raised to their transport position.
First the hand pump hose tted to port HP1, must be redirected from HP1, to port HP2,
and the blanking plug from HP2 must be replaced into HP1, using a 22mm spanner.
Once connected, move an Outrigger Control Lever in the required direction of
movement, and operate the hand pump. When the Outrigger starts to raise, continue
depressing the control lever.
Some hydraulic oil will be lost during this procedure. This will still
allow Emergency operations, but will need to be replaced before full
normal use can resumed.
5. Cage Overload
In the event of the cage being overloaded, an audible alarm will sound and the cage
controls will cut out.
!
To re-start, enough load must be removed from the cage so that the alarm stops
sounding.
In cases where the overload can not be immediatley removed or the cage has fouled,
then the overload override selector switch can be used to move the platform to a safe
position so that the overload can safely removed.
The Key, Motor Run/Deadman and a Control Lever must be operated
at the same time to effect this action

MAINTENANCE
Slew Drive Gears.
The slew drive gear is designed to be largely maintenance free. However, we recommend the
gear teeth be greased on a monthly basis with a high pressure grease. Additionally, the ring
gear and gear box should be greased on a six monthly basis. The grease nipple for the ring
gear is on the top face of the slew gear, set between the xing bolts. It can be accessed by
lifting one of the side covers, and slewing the structure appropriately.
Grease Nipple
The ring gear should be inspected on a six monthly basis for excessive play. It is unlikely there
will be any wear if the machine is maintained correctly.
Grease Nipples
To check the gear, place a payload of approximately 80Kg in the platform. Elevate the lower
boom to approximately half way. Then gently elevate the top boom, whilst observing the ring
gear. Excessive wear will be observed by noticing more than 0.5mm movement between the
inner and outer bearing rings.
Checking Limit Switch Operation.
The limit switches require no maintenance, other than a visual inspection, on a pre operation
basis. This is an important check, to ensure the switch is not mechanically damaged, and the
roller is always in contact with the cam, when not under load.
The switch operation can be simply checked, by observing the LED display when deploying
the stabilizers. As an outrigger foot touches the ground and becomes loaded, the appropriate
light will change to green. This indicates that the switch contact has operated correctly.
Outriggers
under load
Outriggers NOT
under load
If the LED displays green at any other time then the machine must not be operated, until the
fault is rectied.
