INTRODUCTION
Thank you for your selection of Might
equipment.
General Safety Instructions for the
Operation of Power Equipment
The goal of Might is to produce power
equipment that helps the operator work safely
and efficiently. The most important safety
device for this or any tool is the operator. Care
and good judgment are the best protection
against injury. All possible hazards cannot be
covered here. but we have tried to highlight
some of the important items,individuals should
look for and obey Caution. Warning and
Danger signs placed on equipment,and
displayed in the workplace．Operators should
read and follow safety instructions packed with
each product.
Lean how each machine works. Even if you
have previously used similar machines.
carefully check out each machine before you
use it. Get the “feel” of it and know its
capabilities, limitations,potential hazards, how it
operates, and how it stops.
APPLICATIONS
Compaction of concrete slabs
Precast sections
Roadways
Warehouse floors
FUNCTIONSAND CONTROLS
Motor
The motor is controlled by an ON/OFF switch
or push button which is mounted on the motor
below the fuel tank．
The motor speed is controlled by throttle lever
mounted on the handle．
The motor is a 4-stroke unit and must only be
used with Unleaded
HAZARDSAND RISKS
NEVER allow any person to operate the
machine without adequate instruction．
ENSURE all operators read,understand and
follow the operating instructions．
SERIOUS INJURY could result from improper
or care-less use of this machine
! MECHANICAL HAZARDS
DO NOT operate the machine unless all
protective guards are in place．
KEEP hands and feet clear of rotating and
moving parts as they will cause injury if
contacted．
ENSURE that the motor operation switch is in
the OFF position and the spark plug ignition
lead is disconnected before removing the
guards or making adjustments．
DO NOT leave the machine in operation while
it is unattended．
EXERCISE CARE when operating
unit．Exposure to Vibration or repetitive work
actions may be harmfulto hands and arms．
NEVER stand on the unit while it is operating
BE CAREFUL not to come in contact with the
muffler when the engine is hot．since it can
cause severe burns．
ENSURE that repairs to the motor and
machine are carried out by COMPETENT
personnel．
! FIRE & EXPLOSION HAZARDS
PETROLis extremely flammable and explosive
under certain conditions．
ENSURE that petrol is only stored in an
approved storage container．
DO NOT refuel the motor while it is in operation
or hot．
DO NOT refuel the motor in the vicinity of
sparks，a naked flame ora person smoking．
DO NOT over fill the fuel tank and avoid spilling

5
petrol when refueling．Spilled petrol or petrol
vapour may ignite．If spillage occurs，ensure
that the area is dry before starting the motor．
ENSURE that the fuel tank cap is securely
fitted after refueling．
! CHEMICAL HAZARDS
DO NOT operate or refuel a petrol motor in a
confined area without adequate ventilation.
CARBON MONOXIDE exhaust gases from
internal combustion motor driven units can
cause death in confinedspaces.
!NOISE HAZARDS
EXCESSIVE NOISE can lead to temporary or
permanent loss of hearing．
WEAR an approved hearing protection device
to limit noise exposure ．As required by
Occupational Health and Safety regulations．
PROTECTIVE CLOTHING
ALWAYS wear protective clothing and footwear
to prevent the skin coming into contact with wet
concrete．
PROTECTIVE FOOTWARE should be worn to
reduce injuries from penetration through the
sole，contact with cutting objects, slipping,
contact with wet concrete and electrical
hazards．
GOGGLES for eye protection may also be
necessary.
USE waterproof protection for hands and
knees(if kneeling)when concreting ．If your
clothing becomes wet from concrete contact
make sure you change the clothing．Do not
walk about waiting for it to dry．
!ADDITIONAL HAZARDS
Slip/Trip/Fall is a major cause of serious injury
or death Beware of uneven or slippery work
surfaces．
OPERATION
Using the vibrating-beam screed
Once the concrete，with its surcharge，has
been spread,start the motor and manually pull
the beam along the slab．Make sure that there
is always a continuous surcharge along the
entire length of the leading edge．
Generally one steady pass with the screed
should be enough to compact and level the
concrete．
Vibration of the concrete is still necessary to
bring air bubbles to the surface．
Start the motor using the recoil starter. (If the
motor is fitted with an on/off switch this must
first be turned to ON before starting.)
ALWAYS maintain good footing so that you do
not slip and loose control when starting or
operating the machine
CARE AND PREVNTIVE MAINTENANCE
Inspect the rubber anti vibration mounts for
wear or deterioration．
Clean the aluminium beams regularly to
prevent a build up of concrete residue.
SERVICE
The housing weight must be greased after
every 10 hours of operation．Do not over
grease．
Inspect，clean and/or replace the motor air
cleaner regularly, particularly when operating in
a dusty environment．
Inspect, clean and/or replace the spark plug
regularly
Check all fasteners for tightness as the
machine is subject to vibration．
To test run the screed support the beams on a
resilient support at each end. (eg. use two car
tyres.)
CLEANINGAND STORAGE
Keep the unit clean and free of concrete
residue.
Ensure the cooling fins on the motor are kept
unobstructed．
