MQ STREET PRO 1 SAW — PREPARATION/PRE-INSPECTION
PREPARATION / PRE-INSPECTION
1. Read and fully understand this manual,
the safety intructions in particular, and
the engine manufacturer's manual
supplied with the saw.
2. Select the correct blade for each application. If abrasive
blades are used,
MAKE CERTAIN
they are designed for
use on a concrete floor saw. They must be reinforced and
have a hole for the driving pin. When wet cutting with an
abrasive blade,
MAKE CERTAIN
the blade is intended for
wet cutting. Water will destroy a dry cut abrasive blade.
Some diamond blades require water cooling and failure to
do so will destroy them almost immediately. Other diamond
blades can be used with or without water. Refer to the Blades
and Blade Placement sections on pages 18 and 19 for further
information.
3. Handle all blades with care and
NEVER
use a damaged
blade.
NEVER
use an abrasive blade that has been
dropped.
Electric Powered Saws
1.
The motor should be connected to a power source in
compliance with all local electrical codes. This must be
performed by a qualified electrician. After this connection
is made, it will be necessary to check the rotation of the
motor shaft. The shaft rotation
MUST
be
counter-
clockwise
when viewing the motor from the shaft extension
end. If the rotation of the shaft is incorrect make the
necessary changes for the correct shaft rotation.
2.
MAKE CERTAIN
the rated line voltage is at the motor when
cutting. Motors can burn out when the voltage falls 10%
below the voltage rating of the motor. Also use the correct
heavy duty circuit breakers or fuses in the circuit.
3.
MAKE CERTAIN
the correct size extension cord is used.
Undersize wires will burn out motors. Use the following
chart to determine the extension cord size.

WARNING
ALWAYS
use a grounded (3-wire) extension cord and
MAKE
CERTAIN
that the motor is connected to a properly grounded
electric circuit to protect the operator from possible electric shock.
Figure 6. Engine Oil Dipstick (Removal)
Gasoline Powered Saws
1. Clean the
saw,
removing dirt and dust, particularly the
engine cooling air inlet, carburetor and air cleaner.
2.
Check the air filter for dirt and dust. If air filter is dirty, replace
air filter with a new one as required.
3. Check carburetor for external dirt and dust. Clean with dry
compressed air.
4.
Check fastening nuts and bolts for tightness.
Engine Oil Check
1. To check the engine oil level, place the saw on secure level
ground with the engine stopped. The frame platform
must
be level
to accurately check the engine oil.
2. Remove the filler dipstick from the engine oil filler hole
(Figure 6) and wipe it clean.
NEVER!
touch the power cord (Figure 5) with
wet hands
or while
standing in water
when it is connected to a power source. The
possibly exists of electrical shock (electrocution)
even death.
NEVER!
spray water directly on
the electric motor.
