Saw Belt Guides; Replacing The Guide - EFA SB 326 Originalbetriebsanleitung

 Use the torque wrench (C) to slightly tighten
the saw belt.
 Push up guide and lever (D), manually turn
up the saw and thread belt into the guides.
Release the lever (D) (automatically snaps
into working position)
 Use the torque wrench (C) to tighten the
saw belt until the torque wrench snaps in
(wrench quietly clicks). Briefly turn on the
machine to allow the saw belt to automati-
cally adjust its position on the wheels.
 Use the torque wrench (C) to properly
tighten the saw belt.
The tips of the saw belt teeth
are hardened and cannot be
re-sharpened.

5.3 Saw belt guides

The belt saws feature two identical saw belt
guides which, as major belt saw components,
need to be cleaned and checked daily and re-
placed in due time when worn out.
The saw belt guides provide the following func-
tions (see next figure):
 Carbide metal plate (a) - absorbs the sawing
pressure
 2 Carbide metal rods (b) - deflect and guide
the saw belt
 Pressure spring (c) - spring-actuated ab-
sorber of the sawing pressure
 Fibre guide (d)
- Running traces on the carbide metal
- Gap set to 0.6 mm in the factory
- Turn rods (b) if running traces occur

 Worn carbide metal plate (a) (groove marks)
can be turned (all 4 sides can be used).
Turning the plate early prevents cracks on
the back of the saw belt.
 The carbide metal rods (b) cannot be ad-
justed. They may be turned to make best
use of the entire circumference at the top
and bottom ends. Replace worn rods. This is
to prevent cracking and to warrant correct
sawing results.
 Check that the saw belt guide can move
freely.
 Regularly check the fibre guide (d) for wear
and replace as necessary.

23. Replacing the guide

 The illustrations below help to explain how
the entire guide assembly provided to guide
the saw belt (lever, fixture and fibre guide)
can be disassembled for maintenance pur-
poses. In order to maintain a tidier picture,
disassembly is only shown for the rail side.
The assembly can also be uninstalled with
the rail mounted on the saw.
 Open the lids (A) and remove the saw belt
from the guide, see section "Disassembling
the saw belt".

The tips of the saw belt teeth
are hardened and cannot be
re-sharpened. Replace the fi-
bre guide when its gap is
wider than 2 mm.
