PROBLEM
PROBABLE CAUSE
SOLUTION
7 Saw is cutting out-of-square
horizontally.
7.1 Stock misalignment.
7.1 Check for bowed stock.
Re-arrange stock.
8 Blade comes off blade wheels.
8.1 Low blade tension.
8.1 See 6.3
8.2 Excessive feed force.
8.2 See 6.1
8.3 Blade tracking. Too far off wheels.
8.3 Check tracking, adjust if necessary.
8.4 Excessive wheel wear.
8.4 Put straight edge on wheel surface and
check for rocking.
9 Blade stalls in cut.
9.1 Low blade tension.
9.1 See 6.3
9.2 Excessive feed force.
9.2 See 6.1
9.3 Blade pinched by stock with internal
stresses.
9.3 Use blade with extra wide set.
10 Blade vibrates excessively.
10.1 Blade speed too high.
10.1 Lower blade speed.(Occasionally
increasing speed can help.)
10.2 Low blade tension.
10.2 See 6.3
10.3 Not best blade pitch.
10.3 Refer to Saw Cutting Parameter Chart.
If blade pitch is correct per chart:
In solids, try next finer pitch.
In structural's try next finer pitch.
11 Excessive blade breakage.
11.1 Band tension too high.
11.1 Check blade tension display - If
required adjust tension see 6.3
11.2 Excessive feed force.
11.2 See 6.1
12 Blade tooth strippage.
12.1 Gullet packing - blade pitch too fine.
12.1 Refer to Saw Cutting Parameter Chart for
correct pitch.
12.2 Gullet packing - blade brush not
cleaning.
12.2 Adjust or replace blade brush.
12.3 Excessive feed force.
12.3 See 6.1
13 Blade dulls too quickly.
13.1 Blade speed too high.
13.1 Refer to Saw Cutting parameters Chart.
13.2 Excessive feed force.
13.2 See 6.1
13.3 Wrong blade for work piece material.
13.3 Seek advice o f blade supplier or
Hyd-Mech dealer.
13.4 Ineffective cutting fluid.
13.4 Check fluid cleanliness and concentration.
Seek advice of fluid supplier or
Hyd-Mech dealer.
14 No or low cutting fluid flow.
14.1 Fluid level in tank is too low.
14.1 Add cutting fluid.
14.2 Fluid line(s) blocked.
14.2 Clear line(s) with compressed air.
Wear suitable eye protection
14.3 Cutting fluid pump not running but,
corresponding LED at the MEP 32
output lights:
No 24Vac power at output.
14.3.1 Use meter to check voltage from
coolant pump terminal (-x-J13) on
MEP 32 PCB to 0Vac terminal. If
24Vac is not present, check fuse
F14 & if required replace.
Cutting fluid pump not running but,
corresponding LED at the MEP 32
output lights:
24Vac power present at output.
14.3.2 Check coil of contactor K4. If
contactor has latched check 3 phase
power to the coolant pump. If 3 phase
power is present, replace pump.
14.4 Cutting fluid pump running, but not
pumping.
14.4.1 Tilt and shake pump, while running to clear
air and assist priming.
14.4.2 Shut-down and remove pump, check for
blockages.
Check that impeller is intact, replace pump
if necessary.
Shaded actions to be performed
only by qualified service personnel.
