3.3 Installing the Blades
There are three types of blades available for the trowels. Float pans are large style blades,
which hook on over finish or combination blades, used in the earliest stages of work, and are
not pitched.
Finishing blades are used in the final stages of working, and are progressively pitched to
burnish the concrete.
Combination blades can be used throughout the concrete working process. They are used in
place of float pans and finishing blades.
Note: Do not put larger diameter blades on a smaller diameter trowel.
3.3.1 Finishing blades are flat on both edges and can be installed in either direction.
3.3.2 When installing combination blades, orient blades as bellow. This positions the raised edges
of the blade correctly for the clockwise rotation of the machine.
3.3.3 Secure blades to trowel arms with screws (a). Dip threads of screws in grease prior to
installation. This will prevent concrete from cementing the screws in place and will make
removal of the blades easier later on.
Warning: Do not lift the trowel overhead with a float pan attached, as the pan could fall off
and strike personnel working in the vicinity.
OPERATION
3.4 Before Starting
Before starting the machine, check the following items:
All handles are free from grease, oil and dirt.
All control levers are in the neutral position.
All bolted joints are tightened.
Oil level in gearbox
Condition of Ring Guard
Condition of trowel arms and blades
NOTICE: Check the oil level in the engine and machine before starting. The warranties
are VOID if the machine run without oil.

12
3.5 Handle Installation and Adjusting
3.5.1 Un-pack the handle assembly and the lower unit from the boxes. Check to make sure no
damage was done during shipment. Mount the handle assembly to the gearbox on the lower
unit using 10mm nuts that are supplied in a package on the lower unit.
3.5.2 Pull the pitch control cable (A) from bottom end of the tube and remove the cable nut (B)
from the cable. Push the control knob (C) all the way forward (away from the operator) or
turn the twist pitch control handle counterclockwise as far as possible. Connect the cable to
the yoke (D) as shown and adjust the cable nut so the cable is snug and the trowel blades
lay flat (00pitch).
3.5.3 Move throttle to idle position. Remove air cleaner cover. Feed cable through clamp on recoil
cover. Connect throttle cable to engine throttle bracket by placing z-bend through hole in
throttle plate. Clamp cable into throttle casing bracket. Replace air cleaner cover.
3.5.4 On machines with an adjustable handle, position the handle by loosening the knob (E) and
adjusting the handle up or down to suit the operator. Tighten the knob to secure the handle in
position.
3.6 Safety Stop Switch
The switching mechanism of this switch should operate freely and should always be kept in
this condition. With the switch in the OFF position, the engine should not start or run. The
purpose of this switch is to stop the engine in a runaway situation, (i.e. the operator releasing
the handle during operation).
3.7 To Start
Make sure that the machine is equipped with the right blades.
1. Make sure that the main power is connected to the machine.
2. Grip the handle and the Safety Stop Switch.
3. Start the machine by pressing the key switch to “ON”.
4. Never let go of the handle during operation.

3.8 To Stop
Reduce RPM to “0” by moving the speed control. Release the safety stop switch. Turn the key
switch to “OFF”.
3.9 Speed Control
The motor speed can be set on Auto and Manual mode.
Speed Control on Auto: In Auto speed mode, adjust the motor speed suitable for real-time working
conditions, clockwise to increase, counterclockwise to decrease MIN(0 min/n)~MAX(120 min/n).
Speed Control on Manual: In Manual speed mode, turn the handle for adjust speed.
3.10 Pitch Adjustment
To adjust blade pitch (angle) by fast pitch control. Pull the control knob all the way reverse
(towards to the operator) to increases the pitch of the blades. Push the control knob all the way
forward (away from the operator) to flattens or decreases the pitch of the blades.
3.11 Floating Operation
Attach float blades to the trowel arms, and when the concrete has set sufficiently to support the
weight of the trowel, place the unit on the concrete. Start the unit and engage the blades as
previously instructed. Using the tilt adjustment knob to adjust the blades to the float
position-blades should be as flat to the concrete as possible with enough tension kept on the tilt
adjustment cable to prevent the unit from dancing or chattering.
OPERATION
This operation will bring the water and fines to the surface, allowing for a smoother finish when
finishing the concrete.
3.12 Finishing Operation
After floating, allow the concrete to set until it will support the weight of the trowel. Set the
pitch to approximately 1/4” to 3/8” on the blades. If the blades start to dig into the concrete,
decrease the amount of pitch.

5.2 Battery Maintenance
To retain the capacity of the batteries it is very important that the following handling instructions
are observed.
After each use the batteries must always immediately be completely recharged.
This recharging is particularly necessary if the batteries will then be lying unused for around 3
weeks or longer.
Repeated storage without prior recharging will result in the batteries losing more and more charge
power, with the charge power eventually dropping to 20-30% of the batteries original capacity.
5.3 Directions for Battery charger
Connect the charger to the battery via the charging contact.
Connect the mains cable to the wall socket.
The red connection light comes on when charging commences.
The green light comes on when the battery is reday for use.
When the green and red lights are both on, the charger is contiuning with adjustment/
maintenance charging, and it should thus remain connected until the battery is used.
Disconnect the mains cable from the wall socket.
Disconnect the charger from the battery.
Caution: The battery emits explosive gases during charging, so avoid flames and sparks.
The charger must not be exposed to water.
The machine must not be connected to any power source while cleaning.

16
5.4 Lubrication
The long life and successful operation of any parts of machinery is dependent on frequent and
thorough lubrication. Before using the machine, always check the oil and use proper oil with the
correct type and grade as recommended.
NOTICE: DO NOT mix types of oil in gearbox and DO NOT overfill the oil. Damage to the machine
may occur if oils are mixed or overfilled. See Technical Data for oil quantity and type.
5.5 Lifting Trowels
Use and lifting hook(if equipped) when lifting machine. Make sure lifting device has enough
capacity to hold machine (see identification plate on machine for weight).
