MAINTENANCE
The Belle Group Porto Screed is designed to give many years of trouble free operation. It is, however, important that the simple
regular maintenance listed in this section is carried out. It is recommended that an approved Belle Group dealer carries out all major
maintenance and repairs. Always use genuine Belle Group replacement parts, the use of spurious parts may void your warranty.
Before any maintenance is carried out on the machine, switch off the engine and disconnect the HT lead from the sparkplug.
Always set the Porto Screed on level ground to ensure any fl uid levels will be correctly read.
Only use recommended oils (see chart below).
Running In Period
When the Porto Screed is fi rst used from new, the engine oil must be changed after the initial running in period (see engine manual
for full detail). The belt tension should be checked after 4 hours use. If a new belt has been fi tted, it must initially be checked after 30
minutes of use.
Drive Belt.
Remove the belt guard then check the belt tension by placing light fi nger pressure on the top of the belt, as near central between
the engine drive and drive pulley. The belt should defl ect by a maximum of 4mm. If the belt tension requires adjustment, loosen the
four nuts holding the bearings in position. Slide the bearings away from the engine and retighten the four nuts. Once set, check the
belt tension a second time. Then check the pulley alignment. If the alignment is incorrect, loosen the taperlock bushes and move the
pulley to suit. Once the pulley is aligned, retighten the taperlock bushes. Finally, replace the belt guard ensuring it is correctly and
securely fi tted.

Operating Instructions
GB
• Take the Porto Screed to where it is required.
• NEVER leave the engine running whilst transporting or moving the Porto Screed, even if it is only a short distance.
Note that the machine is a two man lift operation. Never attempt to carry the machine on your own. Always seek assistance with
lifting and transporting the Porto Screed.
• Having carried out the checks listed in the ‘pre start’ section and prepared the Porto Screed for use, you may
start the engine.
The Porto Screed is fi tted with a direct drive system. The machine will vibrate at idle speed. To set the Porto Screed for maximum
vibration, set the throttle to maximum.
• Set the throttle to maximum and use the control handle to gently pull the Porto Screed.
NEVER push the Porto Screed, ALWAYS gently pull the machine. This will ensure that you have a consistent fi nish on the surface.
Never force the machine, always allow it to travel at its own pace.
Always make sure that no person or obstruction is in your line of travel. Watch your step to avoid tripping.
USE extreme caution and be observant when working in close quarters or congested areas.
•
To stop the Porto Screed, follow the ‘Start / Stop Procedure’ section.
Hints on Concrete Screeding.
1. Concrete should be placed approximately 1” higher than the formwork over the whole bay area.
2. With the engine running the machine will vibrate along the bay with the vibrating unit leading. The Porto Screed can be supplied
with two end handles or rope handles which are attached to the end frames. These are for two man operation of the porto screed.
The machine will travel with its own momentum with only a little assistance from the operator.
3. A surcharge of 1” of concrete should be maintained in front of each beam at all times. Any surcharge over 1” must be shovelled or
raked
away.
4. If a second pass is required the Porto-Screed should be guided quickly over the slab without stopping to avoid ridges.
