OTHER MAINTENANCE
Guards
Check all guards for damage and proper function daily espe-
cially the blade block. Blade block and cover should be secure
to the saw and not damaged. Lexan side covers on the blade
block should move freely up and down.
Diamond blade
Inspect diamond blades daily for damage, cracks, secure fit
to the arbor, loss of segments, warping or overheating.
If any
blade shows any of these problems, discard the blade and
never use
.
Saw controls
Inspect all controls for proper function daily.
Check all the in-
terlocks for operation especially the red emergency stop
button and engine on/off switch for proper operation
.
Belts
Inspect the blade drive belt and transmission belt for cracks or
signs of wear. The belt tension is controlled by belt tensioners
and does not require adjustment. Inspect the belt tensioners
for free movement up and down. Insure the belt tensioner
bearings roll freely.
Blade shaft bearings
Lubricate the blade shaft bearings with 3 pumps of Lithium 12
based grease every 50 hours.

Cleaning
Clean the blade block of any excess concrete build up after
each use. Keep the handle bars and controls clean and dry.
Immediately clean any spilled fuel from the saw. Keep all
openings and slot on the saw clean and open so air flows free
-
ly through the engine compartment to insure proper cooling.
WARNING
Do not modify the saw! Use only Husqvarna Construc-
tion Products replacement parts. Use of unauthorized
parts may create a danger or damage the engine.
Skid plate
Inspect the skid plate daily for damage, excessive wear in the
blade slot, burrs on the concrete surface side, twisting and free
movement up and down when installed on the blade block.
Replace the skid plate with each new diamond blade. Never
reuse the skid plates or spalling and raveling may result.
Battery
The battery is maintenance free. If the battery ever requires
charging, use only a voltage regulated taper current charger
designed specifically for sealed lead acid gel cell batteries
rated at 2 amps or less (part # 505583501). A standard auto-
motive, or any other type, battery charger not designed specifi
-
cally for sealed gel batteries will cause permanent damage to
the installed battery and void any warranty. Do not leave the
ignition key in the “ON” position as this will drain the battery.
There is a manual recoil start on the side of the engine that
can be used to start the engine if the battery is to low for the
elctric start to function.
WARNING
- Connecting and disconnecting a battery can cause
sparks and short circuits. Do not short battery ter-
minals by allowing a wrench or any other object to
contact both terminals at the same time.
- A spark or flame can cause a lead acid battery to
explode.
- Before connecting a battery, remove metal
bracelets, wristwatch bands, rings, etc. Use gloves
and protective glasses or face shield when working
with a battery.
