Foreword
Quality assurance / machine break in
The machine is the product of extensive engineering development designed to give long life
and unmatched performance. The trowels are shipped fully assembled, and only require
filling with fuel and a brief check of lubricant levels in preparation for operation.
You can help ensure that your trowel will perform at top levels by observing a simple routing
on first use. Consider that your new trowel is like a new car. Just as you would break in a
new car to the road or any new machine to the job, you should start gradually and build up to
full use. Learn what your machine can do and how it will respond. Refer to the engine
manufacturer’s manual for run-in times. Full throttle and control may be used after this time
period, as allowed by material. This will serve to further break in the machine on your specific
application, as well as provide you with additional practice using the machine.
We thank you for the confidence you have placed in us by purchasing a
Beton Trowel machine and wish you many years of satisfied use.

Operation
1 Use
The trowel has been developed to float and finish the edges of concrete floors, up to
perimeter walls, around columns and small areas, eliminating tiring hand troweling and
increasing overall productivity and quality.
2 Safety precautions
❖Always keep unauthorized, inexperienced, untrained people away from this machine.
❖Rotating and moving parts will cause injury if contacted. Make sure guards are in
place. Keep hands and feet away from moving parts.
❖Fuel the machine only when the engine is stopped, using all necessary safety
precautions.
❖The engine must always be stopped before attempting any repair or adjustments.
Ignition switch should be off.
❖To avoid slipping and loss of control when starting the trowel, the operator should
maintain good footing. It is recommended that the operator wear safety shoes for
added protection.
❖Be careful when working around pipes or ducts protruding from the floor or slab
edges. If the trowel blades hit such obstacles, damage to the machine or possible
operator injury may result.
❖When starting the machine, do not exceed 1/3 throttle position. A higher setting may
cause the centrifugal clutch to engage and the handle to rotate.
❖Be careful not to come in contact with the muffler when the engine is hot, serious
burns may result!
❖Over time, the blades will form a sharp edge. Be careful when handling the old
blades.
Never operate the machine in an explosive atmosphere, near combustible
materials or where ventilation does not clear exhaust fumes. Repair fuel leaks
immediately. Refer to your engine owner’s manual for more safety instructions.

3 BT90E Electric Power Trowel Operating Instructions.
The BT90 Electric 230v Power Trowel is driven by a 2.2 Kw Motor. As such it
requires a correct power source to operate the machine. Note that the machine can
draw as much as 24 Amperes on initial start up if the machine has been standing
stationary on wet concrete.
The plug socket provided on the machine is the EU blue three pin safety 32 amp
socket. Plug in your extension cable into the socket. Please ensure the extension
cable is not coiled nor unreasonably long as this will cause power drop to the
machine.
To start rotation of the machine pull in the red hand lever on the left side of the
handle bar. To increase or lower speed use the speed dial on the right side of the
handle bar.
For emergency stop release the red lever.
When operating the machine ensure the power cable is running over the handle bar
and always behind the machine to avoid contact of the cable with the blades. If
contact is made then immediately stop the machine and disconnect the extension
cable and inspect the insulation. If it is damaged then do not continue to use the
machine until the cable is replaced.
If the cable is badly damaged or if the amperes to the machine are insufficient then
the machine has a trip switch that will cut off the power.
Special Note: If the power trowel is fitted with a float pan then the machine may
settle into the wet surface of the concrete and this will create a suction that will put
resistance on the rotation of the electric machine. To avoid this break the machine
free of the concrete prior to starting.

4 OPERATION (Floating)
When the slab has set sufficiently firm that the operator’s footprint leaves a very slight
depression on the surface of the slab, it is ready for the floating operation.
Guiding the machine on the slab is very simple, a slight upward lift of the handle causes the
machine to travel to the left. Holding the handle in the neutral position, will slowly cause the
machine to spin in one spot. Slight downward pressure on the handle causes the machine to
travel to the right. Best results are obtained by covering approximately 4” on each turn. In
other words, let the machine move right or left, backwards or forwards, approximately 4” with
each revolution of the trowels. To fill a hole or cut down a hump, move the unit back and forth
over the problem area.
Under normal operating conditions the machine should cover as much as 1000 sq. ft. in
about 15 minutes. It is recommended that a slight tension on the trowel control cable, (but
not a definite tilt), during the floating operation will cause the machine to operate much
smoother. After the floated slab has set sufficiently, it is ready for the finishing operation.
CAUTION:
Do not let the machine stand in one spot on the soft cement. Lift from the slab
when the floating operation is complete.
5 OPERATION (Finishing)
When starting the finishing operation, never set the trowels up over 1/4” pitch.
After the floating operation, the first thing to do is to remove the floating disc from the blades.
Clean the blades, spider plate and disc from cement paste collected during the floating
operation. Increase the blade pitch up to a maximum of 1 cm for the first finishing operation
and then continue to increase the pitch on the following finishing operations. Continue the
finishing passes until you obtain the desired floor finish. The time required between each
finishing pass is again dependent on the weather conditions and water content of the
concrete etc. If some areas of the concrete set/harden too fast you may apply a small
amount of water using a hand brush as an aid to achieving the finish.
6 STARTING PROCEDURE: *WARM CLIMATE
Open fuel valve on gas tank. Set throttle lever to “Fast” idle position, set choke to closed
position, start engine. Open choke slightly to prevent flooding. Move to “Open” or “Run”
position when engine is warm, increase throttle to maximum operation position (3600 rpm).

8/32
7 STARTING PROCEDURE: *COLD CLIMATE
Follow same procedure as above but allow longer warm-up period –3 to 5 minutes. In cold
weather, oil is much heavier to move and requires more time to work its way into the moving
parts. If maximum power is not attained, allow further warm-up time.
8 STOPPING PROCEDURE
❖Throttle engine down.
❖Turn off stop switch.
9 TRANSPORTING
When transporting the trowel, always keep the handle folded and the blades flat on the floor to prevent
damage to the pitch control system. Always keep the floating disc underneath the blades to protect
them against damage.
CAUTION:
Never lift the trowel by the rotating ring; use the hoist hook or handle provided
on the trowel. Remove the float disc when lifting machine more than 100cm
(40in). The floating disc could fall off.
10 LUBRICATION
❖ENGINE OIL: The long life and successful operation of any piece of machinery is
dependent on frequent and thorough lubrication. Before using the trowel, always
check your engine for oil. Use proper engine oil as recommended in the engine
manufacturer’s manual. Fill crankcase to levels as recommended.
❖SPIDER PLATE : The trowel arm on the spider plate does not require lubrication. If a
trowel arm becomes jammed, this is probably due to a bent arm, which will require
replacement. Appropriate “winterize” steps should be taken if the machine is going to
be stored for long periods of time.
❖GEARBOX: In operation the gearbox lubricant is in a fluid state. When the machine is
stopped the lubricant returns to a gel state. It will only be necessary to inspect the
sealed components if the outside of the gearbox gets too oily or otherwise shows
evidence of a leak. If this happens, clean the machine thoroughly and look for leaks.
Effect necessary repairs immediately. Use SHELL TIVELA COMPOUNDS ‘A’ (0.3L,
10.1oz.) gear oil or equivalent to top up the gear box after any maintenance to the
internal components.

11 STORAGE
The following steps should be taken to prepare your trowel for extended storage.
❖Close fuel shut off valve.
❖Siphon excess gasoline from tank.
❖Start engine until it stops from lack of fuel. This will use up all the fuel in the
carburetor and prevent formation of deposits due to evaporation of fuel.
❖Remove spark plug and pour 2 oz. of SAE-30 or SAE-40 motor oil into the cylinder.
Slowly crank the engine 2 or 3 times to distribute the oil throughout the cylinder. This
will help prevent rust during storage. Replace spark plug.
❖Store the unit in an upright position in a cool, dry, well ventilated area.

Maintenance
1 Preventative maintenance and routine service plan.
This trowel has been assembled with care and will provide years of service. Preventative
maintenance and routine service are essential to the long life of your trowel. Your dealer is
interested in your new machine and has the desire to help you get the most value from it.
After reading through this manual thoroughly, you will find that you can do some of the
regular maintenance yourself. However, when in need of parts or major service, be sure to
see Beton Trowel.
❖AIR CLEANER - Keep air filter clean at all times. Wash away dust and debris using a non-oil
based cleaning solvent. Let the filter dry before re-installing.
❖LUBRICATION –Always check engine oil regularly. Use proper engine oil as recommended.
See chart on this page. Fill crankcase to levels as recommended in manufacture’s engine
manual.
❖SPARK PLUG –Check and clean spark plugs regularly. A fouled, dirty or carboned spark
plug causes hard starting and poor engine performance. Set spark plug gap to recommended
clearance. Refer to engine manual.
❖BELT TENSION –IMPORTANT!
When the engine is switched off, and the machine has stopped, the normal belt play should be
loose. This is due to the clutch type. When the machine is running at full throttle, the clutch will
close in, which tightens the belt causing the gearbox to engage.
When adjusting the belt make sure that the clutch is in alignment with the follower pulley.
Secure belt guard. Tighten all engine mount bolts, and tighten lock nuts.

3 Service
Due to the nature and environment of use, the machines could be exposed to severe
operating conditions. Some general maintenance guidelines will extend the useful life of your
trowel.
❖The initial service for your trowel should be performed after 25 hours of use, at which
time your mechanic (or authorized repair shop) should complete all of the
recommended checks in the schedule above.
❖Regular service according to the schedule above will prolong the life of the trowel and
prevent expensive repairs.
❖Keeping your trowel clean and free from debris is the single most important regular
maintenance operation, over and above the checks in the service schedule above,
that can be performed. After each use your trowel should be cleaned to remove any
dust and debris from the undercarriage and surrounding components. Use of a power
washer will make clean up quick and easy, especially if a non-stick coating was
applied prior to use.
❖In the Service Schedule above, items that should be checked, replaced or adjusted
are indicated by “o” in the appropriate column. Not all trowel models include the same
features and options and as such not all service operations may have to be
performed. For ease of recording place a checkmark (√) through the “o” when the
item is complete. If an item is not required or not completed place an “x” through the
“o” in the box.
