5. Emergency Stop Switches.
Emergency stop switches must operate correctly. Check that each stops the machine’s
controls and that restarting is prevented until all stop switches are unlatched.
6. Emergency Lower/Slew.
With the top and bottom booms raised approximately 500mm each and the unit switched
off, check:
The emergency lower switch located in the basket and ground control stations, lowers
the booms when operated.
The emergency slew, telescopic boom retraction can be operated by using the hand
pump and control lever at the ground control station.
To Reset the hydraulic system after checks;
□ Fully slew the Basket to the right, so that he ram is fully extended.
□ Fully extend the Outriggers while still maintaining Level. (check the bubble)
□ Using the ground controls, fully extend Top, Bottom and Telescopic Booms.
□ Fully extend the Flick Out Boom.
All rams must be fully extended at the same time before returning them to their transit
position.
If the Emergency Lower is used during normal operation, DO NOT use
the machine, Contact your local SNORKEL representative.
7. Emergency Hand Pump.
With the unit set up for working (i.e. outriggers down, under load and the machine level
with wheels clear of ground) it is possible to lower the cage using the emergency hand
pump.
8. Battery Power (Where applicable)
Check batteries are fully charged and topped up with distilled water (these are fitted
under the slew cover on both sides of the platform).
Hydrometer reading should be 1280-1320sg.
With machine level, the distilled water should cover the plates by approximately 6mm.
9. Mains Power (Where applicable)
Check that the voltage and frequency of the power input matches that of the motor.
All extensions must be a minimum of 2.5mmІ, and no longer than 10m due to possible
voltage drop.
10. Petrol/diesel Power (Where applicable)
Check that there is sufficient oil and fuel to complete a full working shift.
