QUALITY ASSURANCE/MACHINE BREAK IN
The Edger Power Trowel is the product of extensive engineering development
designed to give long life and unmatched performance. The Edger Power 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 Power Trowel will perform at top levels by
observing a simple routing on first use. Consider that your new Power Trowel is
like a new car. Just as you would break in a new a 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 an Edger
Power Trowel and wish you many years of satisfied use.

Routine Service Intervals
Due to the nature and environment of use, Edger Power Trowels 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. The chart on page 6 (six) is
handy for keeping a record of the maintenance performed and the parts used
for servicing your trowel.
Regular service according to the schedule above will prolong the life of the
Edger Power Trowel and prevent expensive repairs.
Keeping your Edger Power Trowel clean and free from debris is the single

Henan Master Machinery Co., Ltd
Tel:[phone] www.mastermachinerys.com
8
most important regular maintenance operation, over and above the checks in
the service schedule above, that can be performed. After each use your Edger
Power 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 "○" in the appropriate column. Not all Edger Power
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 "○" when the item is complete. If an item is not
required or not complete place an "×" through the "○" in the box.
All Edger Power Trowel have governed engine speed of 3600 rpm. See
engine manufacturer's manual for exact specifications. Care should be used
when making any adjustments to the Edger Power Trowel not to and lower
travel speed. It will create excessive "out-of-synch" vibrations resulting in
poor compaction,
maneuverability, excessive wear to the machine, and discomfort to the
operator.
Failure to have your Edger Power Trowel regularly serviced and properly
maintained in accordance with the manufacturer's instructions will lead to
premature and void the warranty.
FORWORD
The Bartell Edger Power Trowel, also known as a Mini-trowel/Edger, 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.

SAFETY PRECATIONS
1. Always keep unauthorized, inexperienced, untrained people away from this
machine.
2. Rotating and moving parts will cause injury if contacted. Make sure guards are
in place. Keep hands and feet away from moving parts.
a. Fuel the machine only when the engine is stopped, using all necessary safety
precautions.
b. The engine must always be stopped before attempting any repair or
adjustments. Ignition switch should be off.
c. 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.
1. 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.
DANGER: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.
ASSEMBLY INSTRUCTIONS
Your new Bartell Edger Power Trowel has been shipped to you fully assembled.

Henan Master Machinery Co., Ltd
Tel:[phone] www.mastermachinerys.com

All you need to do is unfold the handle and fasten the knob. Remove any shipping
or packing materials. Be sure to remove and discard the band securing the
safety/stop switch to the left handle. This serves only to facilitate shipping and is
not intended to be a permanent feature. When removing the machine from the
carton, be careful to use the handles to left the unit from the carton. NEWER LIFT
THE MACHINE BY THE RING OR DISC. Filling the fuel tank and a brief check
of lubricant levels in preparation for operation is required.
IMPORTANT: Before running machine with belt installed, ensure that engine
idles properly and that the safety-switch shuts off the engine.
ATTENTION: For any information regarding engine adjustments, please refer to
the engine manual supplied.
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 cause the machine to the 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 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

Henan Master Machinery Co., Ltd
Tel:[phone] www.mastermachinerys.com
11
from the slab when the floating operation is complete.
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.
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).
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.
STOPPING PROCEDURE
1. Throttle engine down.
2. Turn off stop switch.

MAINTENANCE
Maintaining your Edger Power Trowel will insure long life to the machine and its
components.
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 tighten the belt causing the gearbox
to engage.
When adjusting the belt makes sure that the clutch is in alignment with the
follower pulley. Secure belt guard. Tighten all engine mount bolts, and tighten
lock nuts.
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.

LUBRICATION
1. 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.
2. 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.
3. GEARBOX
In operation the gearbox lubricant is in 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.

extended storage.
1. Close fuel shut off valve.
2. Siphon excess gasoline from tank.
3. 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.
4. 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.
5. Store the unit in an upright position in a cool, dry, well ventilated area.
