3. Definitions .
Supply line: (Red coloured airline) delivers compressed air to braking system.
Return line: (Blue coloured airline) allows air to be released after brake application has ceased.
Electrical line: supplies electrical power of all lights and in some cases trailer legs.
Shock Loading: is result of poor operational skills, ramming back into turntable too hard and resultant energy is transferred to load or drivers. This can result in damaged product or serious injury to driver (often spinal)
Hot spotting Clutches: is result of poor operation by driver, commonly caused by driver “Riding the clutch“, causes raised sections of metal on either Pressure Plate or Flywheel, this causes various degrees of shuddering of vehicle when moving from stationary position.

4. Coupling to Trailers 1.Locate Trailer
2. Determine if trailer can be backed under . Any obstructions removed that have been placed in front of trailer.
Trailer needs to be in a position, so it can be backed under squarely. Backing under a trailer squarely aligns up pin and turn table and prevents damage to the mud guards.

5. Coupling to Trailers
3. Check turntable. Ensure jaws are open. Jaws will not lock properly if they are not fully opened first.
Trailer height Stop reversing prime mover when the turntable is close to the front of the trailer.
* Apply park brake
* Check height of trailer to ensure there is a slight interference (gap) between turntable and skid plate.

6. Coupling to Trailers
If turntable and skid plate have excessive gap, damage to jaws on turntable will result.
If turntable higher than skid plate, damage to air fittings and front of trailer will result.
Correct this by raising or lowering turntable airbag.

7. Coupling to Trailers Chock wheels on trailer.
Ensure wheels on trailers have wheel chocks or have spring brakes applied.
If trailer is not anchored in position, it could move rearwards as the prime mover backs underneath, causing damage to the legs of the trailer

8. Coupling to Trailers Connect Airlines. Connect (manually) airlines.
Release park break. Get back into truck & release park brake on truck and trailer, to get airflow to trailer brakes.
Complete Tug Test again, complete another tug test, using trailer service brakes applied. To ensure trailer brakes are operational and Tug/Shunt vehicle is hooked to trailer properly.

9. Decoupling Trailers
Position trailer in drop off position, the trailer needs to be on level ground. To reduce risk of trailer rolling forward or back and causing damage to legs. Check position of Tug vehicle, Check that both Tug and trailer are in a straight line and on ground level. Less risk of damage to guards and turntable if remove in straight line.
Release turntable, ensure jaws are fully opened.
Decouple Trailer. Deflate airbags and drive out from under trailer. Prevent damage to jaws and mudguards.

10. Pre-start Procedure
Operators after making an initial inspection of vehicle for the first time they are using it (it is expected to have been inspected by DGL employee at beginning of each shift).
Each operator is expected to examine vehicle for any defect which would be obvious to operator (only to operators' skills).
After completion of prestart inspection, operator is to turn on ignition and wait for vehicle computer to run its internal checks.
Only after this has occurred may the operator start the vehicle.

11. Operating Tug/Shunting Vehicle
As there are various types of vehicles available to use depending on Stramit site. It is recommended that a consultation with a DGL employee, as to how to raise and lower turntable operates, the turn table lock and release works.
In general most turntables are operated by a rocker type lever it may be on the dash or next to driver.

12. Operating Tug/Shunting Vehicle
When driving the Tug /Shunting Vehicle, engaging the correct gear is critical to safe operation and movement of both the vehicle and trailer. What is often done by operators, is to select incorrect gear for initial moving from a stationary state. Selecting a high gear such as 3rd , not only does that seriously damage to the clutch or flywheel by slipping the clutch and creating Hot Spots .

13. Operating Tug/Shunting Vehicle
Commonly operator use 2nd as gear of choice to start moving from stationary state.
Whilst this is generally accepted practice, it is recommended that 1st be used so as to minimise damage to gearbox and drive line system by overloading these sections of Vehicle MUA (main unit assemblies).
These components of Vehicle are very expensive to replace or repair.

14. Operating Tug/Shunting Vehicle
Operator must select either 1st or 2nd gear ( in normal range) when starting to move from stationary state.
Operator must wait for air pressure to have reached its operating minimum before moving off to do work.
DO NOT ATEMPT TO MOVE VEHICLE UNTIL AIR PRESSURE WARNING DEVICE HAS CEASED SOUNDING!!
