Important Tips to Remember
■ Do not allow the engine to run out of fuel as this may cause
problems with starting. Always maintain an extra supply of
fuel on the job site.
■ Always keep the DuoScreed moving backwards during
operation. Allowing the DuoScreed to vibrate in the same
location for too long will cause it to sink into the concrete.
■ When using the DuoScreed with low slump (dry) concrete do
not attempt to walk it quickly across the slab. Walk slowly to
allow the vibratory action to consolidate and level the slab
surface. When using the DuoScreed with high slump (wet)
concrete you will be able to walk the machine across the slab
at a faster pace.
■ In applications where the Duoscreed is being used as a wet
screed it is recommended that grade or height of the concrete
slab be adjusted with a laser device.
■ Proper vibratory force is essential to producing a
level , hard ,
durable slab. If the DuoScreed is vibrating too strongly the
eccentric weights will require adjustment. Refer to the
troubleshooting section of this manual.
■ When screeding using forms or rails, always size your screed
blade appropriately for the job. It is best to have the blade
extend beyond the forms, by about 6-inches on each side.
■ When screeding make sure the blade is kept straight. DO
NOT let blade turn.
■ DO NOT run the DuoScreed with one part of the blade on
forms and the other on base. The blade must either be placed
on forms or float (wet screeding), but not a combination of the
two techniques.
■ DO NOT stand in the concrete with the engine throttle
engaged. This will cause the DuoScreed to sink.
■ If the concrete appears too wavy, you are moving too slowly,
increase your backing-up speed.
■ Always keep the workers back far enough too allow the
operator to see the cutting face of the blade as it rides on the
wet screed base.
■ The operator should keep the screed blade about 1/8 to 1/4
inch above the concrete base at all times.
■ Should the DuoScreed stick to the wet concrete slab, DO
NOT attempt to lift it. Quickly increase engine rpm's while
pushing forward on the handles to free the machine.
