Machine Functions
The ANGLEMASTER has three separate motors driving the grind stone, traverse and
coolant pump respectively. Each has a separate start/stop button on the control panel.
Grind Stone
Directly driven by the main motor at up to 3800 rpm.
Traverse
Powered by a motor/gearbox unit under the grinding head carriage. Drives along a xed,
damped chain run. Traverse is physically engaged using the over-centre lever on the left
front of the carriage.
Coolant pump
Fitted into the top of the coolant reservoir/settlement tank which is located inside the
cabinet in the base of the machine.
Emergency stop
Pressing the large red mushroom headed button will stop ALL motors. The button will be
locked into the off position. No motors will start when their buttons are pressed until the
E-stop is released by twisting the knob counter-clockwise.

1.1 Always wear eye protection when operating the machine.
1.2 Never leave rags or tools on the machine or wear loose clothing that could become caught
up in the bedknife, grinding stone or shaft.
1.3 Never allow combustible materials to be placed on or around the machine
1.4 Always ensure that all parts of the bedknife being ground are securely xed.
1.5 Never use the machine for any purpose other than that for which it was designed
1.6 If large units are to be ground, ear defenders should ideally be worn.
(The maximum noise, with a heavy cut on a 36” bedknife has been measured at 85
decibels).
1.7 Ensure that all electrical connections are sound and that cables are safely routed.
1.8 NEVER t or use any grinding stone other than those supplied specically for use on the
ANGLEMASTER.
1.9 NEVER t or use a grinding stone that has been dropped or damaged in any other way
1.10 Always mix and use coolant according to the manufacturer’s instructions.
1.11 Never allow coolant to wash over the control box or other electrical parts.
Extreme caution should be used when removing a bedknife from the ANGLEMASTER.
Ideally protective gloves should be worn.

2. Set Up and Installation
2.2 Location
The machine should be installed in a well-lit area, set up on a solid oor base of concrete
or similar. Wooden oors should ideally be avoided.
Using a spirit level, laid across / along the traverse rails, the machine can be leveled easily,
suitable metal packing may be placed under the cabinet chassis feet.
2.1 Handling
The weight of the machine is indicated on the plate on
the front of the machine.
If the machine is supplied crated, it can be moved by a
suitable forklift or pallet truck under the crate base (skid).
Once the lid and sides of the crate have been removed,
the machine remains bolted to the base (skid).
LIFTING WITH CHAINS/STRAPS/FORKS MUST ONLY
BE CARRIED OUT AS INDICATED BY LABELS ON
THE MACHINE NOT BY MEANS OF THE TRAVERSE GUIDE RAILS.
Hex head
bolt
2.3 For transit purposes, the blade-mounting bar is locked in position at both ends. Some units
may be shipped with a hex head bolt in the right hand clamp. If so, the clamp lock down
lever is in the tool drawer of the machine cabinet. Remove replace the hex head bolt with
the lever and tighten down.
The hex head bolt on the left-hand clamp should be eased off and adjusted to permit
rotation of the mounting bar with a small amount of resistance.
Do not release the right hand clamp (lock down lever) until the weight has been taken on
the angle control lever. For all subsequent use only the lock down lever will be used to hold
the mounting bar in position. If the lock down lever does not appear to be applying enough
force, the hex head bolt on the left-hand needs to be a little tighter.

2. Installation (Continued)
2.4 Electrical Supply
USE A QUALIFIED ELECTRICIAN.
All motors are dual cycle 220-230V 50/60Hz, single phase induction motors (Except
variable speed traverse motor on DX models which is three phase).
Electrical connection should be via the electrical cable/plug/socket provided and should be
to a 20 Amp breaker.
The main grinding head motor is overload protected, whilst coolant pump and traverse
motors are independently fused.
Ensure that any cable / conduit run to the machine constitutes no hazard to operator or
other personnel.
The machine MUST BE EARTHED.
2.5 Coolant
Check the location of the settlement tray in the
coolant tank on the shelf in the cabinet under
the left-hand side of the machine. Check the
connection of the coolant supply hose to the
pump outlet.
The soluble additive may be used in the coolant
tank and should be mixed according to the
manufacturer’s instructions (at 1 –1 capful of
additive per FULL tank of water). This uid is
suitable for all types of blade grinding and has
good rust inhibiting properties (if used according
to instructions).
Do not exceed the recommended concentration
as this may lead to “loading” of the grindstone
during usage, which may in turn affect grinding
results.
Sediment in the coolant tank should not exceed ”. Surplus liquid should be returned to
the tank and solid deposits removed at regular intervals, depending upon workload.

3.1 General
3.1.1 The ANGLEMASTER has a capacity of 40” between mounting brackets for complete
bedknife/bedbar assemblies, or 42” for plain blades clamped directly to the mounting bar.
3.2 Mounting a bedknife
3.2.1 The machine is equipped with adjustable, universal bedknife mounting brackets
(adjustable quadrant brackets may also be supplied) which can easily be set to correspond
with bed-bar xing holes. In this way the bedknife is supported on the machine in a way
that resembles, as closely as possible, its mounting in a cutting unit. Special adapters are
available when required for certain units.
3.2.2 Attach adjustable support plate (2) through horizontal slot using locking knob A /
adjustable “kip” lever (3).
3.2.3 Fix either tapered pin (4) or cup (5) to adjustable support plate (Tapered pin ts all
bedknife assemblies which either bolt on or locate over a male pivot pin; Cup support is for
bedknife assemblies which mount similar to Toro 216, Spartan, 3500, 6500 etc).

3. Setting Up (Continued)
3.2.4 There are two alignment stops at the front face of the mounting bar. Rotate the tabs so that
they stand above the top face of the mounting bar.
3.2.5 Using the bedknife, draw the stops out as far as they will go
(only slight pressure is required). Adjust the nut on the back
of the stops to adjust the travel.
The bedknife should be set to overhang the mounting bar
such that the back of the trough lines up with the edge of
the mounting bar (the leading edge of the bedknife will be
around 3/8” - 1/2” forward of the front edge of the mounting
bar). This should ensure that the stone will not grind the back of the bedknife.
3.2.6 Switch on the electromagnets. The bedknife assembly is now held so that it can be easily
mounted.
3.2.7 Universal Brackets
If using the Universal Bedknife Mounting Brackets:
Slide the mounting bracket assembly to the bedknife
assembly and locate bedknife using tapered pin or cup
support (according to it’s mounting type).
3.2.8 Lock the bracket end to the Anglemaster mounting bar,
then lock the support plate in position using locking knob
/ adjustable lever.
3.2.9 Rotate the mounting bar forward to improve
to improve access and adjust the height and
angle of the jacking screw assembly so that
the jacking screw end extension aligns with
a suitable point on the back of the bedknife
assembly. Lock in position with 2 knobs.
Loosen locking nut, adjust jacking screw against
the rear of the bedknife assembly with just
enough pressure to keep the lower front of the
bedknife assembly against the Anglemaster
mounting bar (to stop it swinging when the bar is
rotated) re-tighten locknut.
