General description and facilities
This vehicle has a forward control cab which, in addition to seats for a driver and one passenger, has an extra seat for occasional use by a third man.  Double rear doors provide access to the separate box body which has a translucent roof and is fitted with aluminium racks and cupboards for tools and stores.  Compartments are provided for the accommodation of generator, pump, Rods, Duct and propane gas cylinders.  A Ladder, Extension No. 1 can be stored on a shelf over the nearside racking.  Two positions are provided at the forward end of the body for trolleys holding Cylinders, Air.  A tool board is fitted and adjacent to it is a screened off area for the use of a low pressure boiling ring which may only be used if there are no flammable materials in the body and if only aids driven by propane gas are carried.
A switch in the cab operates all four direction indicators simultaneously, to provide a hazard warning when positioning the vehicle at a work site before the permanent warning signs are laid out.  It is not for prolonged or continuous use.
Some early models are fitted for duct rodding.  These should be modified as outlined in TDB Branch memo. 7/68.

This instruction described the 1 ton utility vehicle Type 2 (Fig 1). This vehicle supersedes the type 1 vehicle and is designed for the use of 2 man parties on maintenance jointing duties.

2. CAB
The cab has quarter lights giving good all round vision and angled doors which do not project beyond the sides of the vehicle. Figs 2 and 3 show the interior and the folding near side seat for easy access. The vacuum gauges for front and rear brakes are on the instrument panel (Fig 4). Main lights and horn operate from the controls to the right of the steering wheel, whilst the direction indicators control is to the left. The hazard warning control together with its warning lamp is fitted conveniently to the drivers right hand adjacent to the switches for panel lights, windscreen washer/wiper, cab heater, and interior lights. The diesel engine is started by means of the key which operates the electric starter when twisted beyond the running position against spring pressure. A “cold start” device is fitted behind the cab on the off-side. When pulled, this feeds extra fuel to the engine to assist starting. The engine is stopped by pulling the control marked “STOP”. This cuts off the fuel supply.

The body is fitted at the rear with double doors for access and with a trap door for “Rods Duct”. Also at the rear is the spare wheel and mounted on the spare wheel carrier framework are the extension sockets for trailer tool carts and other trailers. (Fig 5).

The budget key clip is mounted on the off side door which also contains the ventilator. (Fig 6) . Folding steps with treads of expanded metal are hinged to the vehicle floor so that they stand adjacent to the double doors when travelling. The hinges have been placed as close as practicable to the sides of the gangway to reduce any tripping hazard as far as possible. A grab handle is fitted on the off side of the door opening.

Fig 7 shows one air cylinder mounted in it's trolley stowed against the front bulkhead. Alongside it is the storage for the second air cylinder and trolley. (See Mechanical Aids N9540 and C1035.) Above the nearside air cylinder storage may be seen the forward roller. This is used in conjunction with the rearward roller (Fig 8) shown in its working position, to load the Ladder No 1. The rearward roller hinges into, and is stowed within, the near side racking. The ladder is pushed up over the two rollers into the vehicle and the rear end is lifted and slid sideways on to the ladder shelf. Ladder lashing points are provided. The central flap may be closed when long ladders are carried and both flaps closed when ladders 4A or 5 only are carried. The open space under the forward end of the ladder rack is used for carrying long tools such as digging bars, spades, road signs, and guards. Clothes hooks are provided towards the rear end of this compartment.

The sub-divided compartments to the rear of the vehicle are used for small items such as testers, telephones, hand tools, and for various small stores. The floor area is used for heavy items and for the storage of one gas cylinder near the door. This is the working cylinder for gas plumbing equipment. Fig 9 shows the off side racking. The forward compartments are for bulky items of stores. The two compartments on either side of the wheel arch are for mechanical aids. The cupboard is for domestic items and stores or tools of a more delicate nature, papers etc.

Fig 10

The compartment over the wheel arch contains the domestic gas cylinder and regulator. Gas from this cylinder is fed via a flexible connexion and permanent piping to a gas ring (Fig 10) . The ring and regulating tap are protected from items on the bench top by a vertical fence. Heat shields protect the vehicle body and bench surface and the flame is shielded from draughts by a plate fixed to the front of the bench.

Underneath the bench top is a shelf for small items. This runs the entire length of the vehicle, alongside the duct rod storage compartment. An access hole at the forward end allows small items, inadvertently put into the rod compartment to be recovered.

At the back of the bench is a vertical tool board.

The compartment on the near side is for the carriage of Lamps Road Caution (Paraffin type) and paraffin fuel in containers.

For details and precautions see M0023.

The hazard warning control operates all the four indicators simultaneously. This should only be used for short periods permanent warning signs have been erected. (See M0028)
