The weight of the machine is given on the Manufacturer's data plate together with the other technical information. Motor-hoe can be transported to given place by means of transport wheel (Fig 14 part. 8). Switch off the engine before transporting the machine.

HOW TO ASSEMBLE YOUR MOTOR-HOE Unless otherwise agreed, the motor-hoe is delivered disassembled and placed in a packing case. For assembly to be completed, the step by step procedure is as follows :

TRANSFER WHEEL (Fig. 2 A and 2 B) Take from the packing box the support wheel complete with wheel (1) and insert it in the front seat of the

frame (A). Fit the spring (2) and secure it with the washer (3) and the cotter pin (4) into the housing hole. The wheel support is in the transport position as shown in Fig. 2A. To shift to work position pull it towards the wheel support (1) and turn it to the right until it stops. See fig. 2 B. The spring, washer and cotter pin can be found inside the bag accessories.

SPUR (Fig. 3) Insert the spur (1) in correspondence of the hole of the frame (A). Secure with washer (2) and with the R pin (3) you can find in the accessories bag.

HANDLEBAR ASSEMBLY (Fig. 4): To assemble the handlebar (1) on the tiller frame, perform the following steps:

In the upper hole to pass the screw (2) in the grommet (3) with already entered the control cables and then secure it with the nut (4). Use the lower slot screws (5) inside of the knobs (6) and washers (7). All these pieces for mounting handlebar with the exception of the grommet (3), are present in the envelope accessories inside the packaging box. To fit definitively the handlebar (1) to the corresponding support (8) you need to lower the lever (9).

CONTROL CABLES ASSEMBLY (Fig. 5 - Fig. 6): The two cables are already installed on the unit and must be connected to the corresponding levers.

FORWARD (Fig. 5) Insert the wire (1) with the terminal T-slot (2) of the lever (3) pre-mounted on the handlebar. Place the cylindrical terminal (4) into the seat of the lever (3) and give a firm tug to lock it. Then pinch the wire adjuster (5) into the seat (A) of the lever, by doing downward pressure.

REVERSE (Fig. 6): Insert the wire (1) with the cylindrical terminal into the slot (2) of the lever (3) pre-assembled on the handlebar. Place the cylindrical terminal (4) into the central seat (A) of the lever (3) and give a firm tug to lock it. Then insert the log thread (5) into place (B) of the lever.

THROTTLE ASSEMBLY (Fig. 7) The throttle wire is already mounted both on the engine inside the throttle device (1). Such a device is fastened in the hole (A) of the handlebar with the screw (2) and locked with the nut (3).

ASSEMBLY THE HOE TILLER (Fig. 8) Clean the tiller hubs and the tiller-shaft; apply some grease to make mounting and tiller removal easier in the future. B&S 800 / Kohler SH265 engine model (fig. 8/A): insert the rotavator (1) making attention the knives have the sharpening side turned to the front part of the machine and block the rotavator with two pins (2) assembling the extra-wide tines (3) and fix it with 1 pin as well (2). Then block the tree saver disk (4) with 1 screw (5) and 1 nut (6). Repeat the same operation for the rotavator on the other machine side. Other engines (fig. 8/B): the rotavator (1) is already assembled with nr. 2 screws and the same number of nuts so you only need to assemble the extra-wide tines (3) and block it with pin (2) and fix the tree saver disk (4) with screw (5) and nut (6). Repeat the same operation for the rotavator on the other machine side. N.B. = please note it is necessary to assemble the pin as shown in the picture placed in the centre of the page, i.e., with the protection stopping device turned in the same direction the rotavators are turning, in order to avoid the pin to open during working operations.

ASSEMBLY OF THE TINES GUARD (Fig. 8 A) Only tillers with cm. 75 rotavator. Remove the packing box enlargement widening tines guard (1) with pre-assembled screws (2). Mount it by aligning the screws (2) with cage nuts (3). Repeat the same operation with the widening tines of the other side of the rotavator.

CONTROL ADJUSTMENT : (Fig. 9) Attention! The rotavator has to start working only after having operated on the control levers. Such operation can be performed by acting on the handlebar cables (1 Forward speed) 2 (Reverse speed) register. Furthermore the lever controlling the digging speed (3) should start the rotavator only after having performed half its way. When the lever (3) and the lever (4) are held together, i.e. on working operation, the belt stretcher load-spring for forward speed (5e 6) should be extended for about 8-10 mm. If the handlebar register is not enough to obtain any conditions, please go on another adjustment.

FORWARD: screw or unscrew the adjuster (7) or (8) on the wire (1).

REVERSE: screw or unscrew the adjuster (9) or (10) on the wire (2).

HANDLEBAR ADJUSTMENT (Fig. 10) The motor-hoe handlebar can be both side and height adjusted. Before starting any work it is a good standard operating procedure to adjust the handlebar to the operator's requirements so that the machine could be easily handled.

LATERAL ADJUSTMENT : The lateral inclination of the handlebar allows the operator to keep off the cultivated ground and not to squash the vegetation around. Go on raising the lever (3) to unlock the handlebar (2) from the support (1). Turn the handlebar to the desired part and lower the lever (3) to lock it.

HEIGHT ADJUSTMENT : in order to unlock the handlebar (2) you need to turn the handles (4) to loosen them .

Raise or lower the handlebar in the desired position (the standard adjustment is at the sides height/level). To settle the right position, tighten the 2 handles.
