Page 13: Transport Safety On Public Roads
The fan wheel space is protected against access by a hinged cover with a terminal switch. CAUTION!! If the engine is turned off, the fan wheel runs freely out. Do not open the spiral casing of the fan wheel until it stops. Controls The leaves exhauster can be controlled by means of controls installed on the engine console. -
Page 14: Transport Position
Always before coming to a public road it is necessary to remove all mud and accumulated sediments, especially from trailer tires. Transport Position First make the machine ready for transport: turn the engine off; couple the trailer on the towing bracket ball, or ... -
Page 15: Putting Aside And Parking
For a braked variant: connect the brake safety rope to the buffer, frame or towing bracket in rear of the towing vehicle. This rope of the overrun brake system should be led directly to the towing vehicle and freely for all reciprocal movements both of the trailer and the vehicle. -
Page 16: Trailer Checks Before Ride
While loading on a transport vehicle, no persons are allowed to be under the trailer or in its close vicinity – risk of accidents. Trailer checks before ride The driver is obliged to carry out the following checks, in particular: ... -
Page 17: Storage
Machine ready for transport Set the discharge duct forwards Put the suction hose in holders Put the hose nozzle in its holder and secure it with a clip and secure it with a cotter pin Before starting the battery should be fully charged. Remove the battery and let have it recharged by an authorised person. -
Page 18: Before Putting Into Operation
Discharge the used oil into a special bin. Dispose used oil and used filters always in accordance with relevant valid laws and local regulations. Remove any spilled oil and clean all oily spots. Always put the machine aside on a flat and solid floor and block its wheels against unwilling motion by means of scotch blocks. -
Page 19: Before Putting Into Operation
Check the engine oil level with a dipstick and refill if necessary. The oil level should be between both marks (MIN and MAX). Check the suction hose for tightness – any untightness reduces suction performance essentially (wear, damage). For putting the suction hose on its adapters use always binding bands. In case of any damage on the exhauster contact your dealer or authorised service. - Page 20 Any servicing can be done only if the machine was put out of operation and its chassis blocked against unwilling motion. In case of a braked trailer, use its parking brake or chock both travelling wheels. Do not step on the chassis frame! It is strictly forbidden to test the suction draw or air flow by extremities.

Page 21: Putting Out Of Operation
At cold starting, especially in winter time, do not increase the engine speed but first let the engine running in idle speed to warm up. Do not leave the machine unattended. At the first start there is much more air in the intake manifold and on this account the engine may not roar to life immediately when turning the switch key for the first time. - Page 22 Is strictly off limits test run of the exhauster puting near the suction hole to parts of the human bodies , stoking limbs to the suction-fan , also to the flow of air. Set the exhauster so that the suction hose has optimal access to the leaves to be sucked.

from operation. To touch these components first wait for 10 min at least to let them cool down. EXPLOSIVE VAPOURS Refer to your local fuel supplier for the MSDS sheet. Fuel used for this engine is inflammable material with its class of danger I. If fuel refilling is required then put the machine out of operation and let the engine cool down. -
Page 25: Driving Engine
Driving Engine This exhauster is powered by an air-cooled four-stroke single petrol engine KOHLER CH740 built in the rear part of the machine frame. The engine is equipped with an electric starter. One 12 V battery is installed aside the engine with its metal fuel tank. -

Page 30: V-Belt Tension
It is strictly forbidden to carry out any welding works on the axle, overrun mechanism and coupling device – damaged parts must always be replaced. V-belt tension It is necessary to pay special attention to the routine maintenance and proper belt tension adjustment because the V-belts on this machine transfer the engine torque to the fan wheel. - Page 31 1 – fixing bolts 2 – stretching bolts For belt tension adjustment remove the side cover fixed here over the belt drive. Check up optimal slack of belts. It should be 15,5 mm just in the middle between both pulleys at down pressure of 50 N. If the recommended slack value is exceeded, tighten the belts by means of necessary replacement of the driving engine in its longitudinal grooves.
- Page 32 For proper belt tension first check up also alignment of pulleys (their faces). Align the pulleys (their faces) by means of a straight-edge rule. Pay your attention to this alignment also after any engine displacement. At reassembly do not confuse the RH side pulley (engine) with the LH side pulley (fan).
-
Page 33: Maintenance Intervals
Loosen the locking nuts (3- 2x) on the stretching bolts (2 - 2x) and move the engine in its slot holes as necessary. Go on displacing the engine to set up optimal belt tension/slack of 15,5 mm at down pressure of 50 N. Having reached the recommended belt slack value and proper pulley alignment, retighten the fixing bolts on the engine (1 - 4x) and the locking nuts (3 - 2x). -

the locking nut and remove the filter element. Check the air pre-cleaner every 25 working hrs as follows: Loosen the pre-cleaner carefully from its cap, remove deposits from its element and wash it in warm water with a non-foamy detergent. Rinse the filter element with the water, press the water out and dry it up. -
