TROUBLESHOOTING

PROBLEM

POSSIBLE CAUSE

REMEDY

No hydraulic pressure in system

1. Hydraulic relief valve setting incorrect

2. Hydraulic relief valve relieving below

set pressure

3. Hydraulic cylinder piston rings and

seals worn

4. Decompression valve stuck open

1. Reset to specifications

2. Repair or replace

3. Replace worn rings and seals

4. Repair or replace

Hydraulic pump making excessive noise 1. Closed or restricted liquid supply line

2. Leak in fluid intake line

3. Leak at pump shaft packing and/or

seals

4. Hydraulic fluid level low

5. Fluid viscosity too high (especially in

cold conditions)

6. Pump coupling loose or worn

1. Check supply valve and/or strainer or

filter

2. Repair

3. Repair

4. Add hydraulic fluid to proper level

5. Use hydraulic fluid with a lower vis-

cosity or install a low density immer-

sion heater suitable for hydraulic fluid

(contact Tomco for more information)

6. Tighten or replace

Excessive wear or breakage of pump

parts

1. Abrasive material in hydraulic fluid

2. Hydraulic fluid does not meet specifi

cations

3. Other

1. Replace or clean hydraulic fluid filter,

clean hydraulic reservoir and change

hydraulic fluid

2. Use hydraulic fluid with a viscosity of

150-300 SUS (ISO 32-68) @ 100 ºF

(37.7 ºC) such as Rando HD68 or

equal

3. See problem

Hydraulic pump making

Hydraulic fluid leaks from around pump

shaft or housing

1. Pump shaft packing and/or seals

worn

2. Head packing seals damaged

3. Excessive case pressure due to re-

stricted case drain flow to tank

1. Replace worn packing and seals

2. Replace damaged head packing

seals

3. Clean case drain line

Control Panel Message

“MOTOR OVERLOAD”

1. Excessive hydraulic pump pressure

2. Moisture on extrusion die or inside

compression cylinder

1. Check pump pressure control set-

tings

2. Remove extrusion die, clean and dry

die and inside of compression

cylinder thoroughly and reinstall,

being certain to torque according the

procedures on page 4.12

Control Panel Message

“LOW OIL LEVEL”

1. Possible leaks in hydraulic system

1. Repair leaks, add hydraulic fluid to

proper level
