Husqvarna SMB 70, SMB 70 E Chainsaw User Manual

Band Wheels (FIG 6)
The bandsaw blade runs over two band wheels
(26), which are made of cast aluminium and are
balanced to provide smooth operation. The band
wheels are equipped with bearings, and are
adjustable, partly to tension the bandsaw blade
and partly to adjust the correct alignment of the
bandsaw blade.
The band wheels are fitted with scrapers so that
sawdust and the like does not penetrate between
the bandsaw blade and the band wheel.
One of the band wheels is powered by the
engine/motor via an adjustable belt.
Bandsaw and Band Guide (FIG 6)
Two band guides (8) are used to keep the
bandsaw blade (9) in the correct position during
cutting. One of the band guides is placed in front
of the powered band wheel and ensures correct
entry onto the wheel. The other band guide is
adjustable and is positioned above the bandsaw
blade before it runs onto the log. This band guide
absorbs the forces from the log and prevents the
bandsaw blade from shifting.
DESCRIPTION
Handlebars (FIG. 5)
The saw carriage is operated and moved for-
ward with a vibration-free steering handlebar (5),
located on the carriage’s right hand side. The
handlebar is equipped with start and stop
controls (4) for the bandsaw.
Cleaning Tank (FIG. 5)
The saw carriage is equipped with a cleaning
tank (3). The tank is located beside the handle-
bars. Cleaning fluid is applied to the blade by
opening the tank valve.
Propulsion
Petrol Engine (FIG. 7)
The one-man saw is run with an air-cooled four-
stroke engine (15). A clutch is located on the
engine’s drive axle that starts, stops, and brakes
the bandsaw blade. The speed of the engine is
regulated with the operating control on the
handlebars. See the enclosed manual for a
description of the engine.
Electric Motor (FIG. 8)
The one-man saw is powered by a 3-phase motor
(37). The motor is started and stopped with the
start and stop buttons on the distribution box,
which has built-in motor protection. There is also
a connection for an electric cable with single
polarity reversal (FIG. 8A), and a main switch
(FIG. 8B.). A clutch is located on the motor’s axle
and starts, stops, and brakes the bandsaw blade.
