Caution!

Residual Hydraulic Energy

Residual energy must be released from the pressurized hydraulic fluid
before any maintenance or repair work is done on the log splitter.
Hydraulic fluid can remain highly pressurized even while the splitter's

motor is off. Escaping pressurized hydraulic fluid can penetrate skin and
cause serious injury.

To release residual hydraulic energy:

1. Shut off splitter motor (tractor motor if splitter is a three-point
hitch model).

2. Move control valve back and forth, from one limit of travel to the
other, at least four times.

3. Hold valve for three seconds at each limit of travel.

&WARNINGS

Escaping pressurized fluid from hydraulic system leaks can have enough force to
penetrate skin and cause serious injury or death.

Hydraulic fluid can remain highly pressurized while splitter motor is off.
Never use your hand or any part of your body to check for hydraulic system leaks

while the system is pressurized.
Get professional medical help at once if hydraulic oil penetrates anyone's skin.
Always release residual energy from pressurized hydraulic fluid before doing any

maintenance or repair work on the log splitter.

What You

SHOULD Do

What You

SHOULD NOT Do

TIMBERWOLF Log Splitters'

• Don't put any part of your body within the splitting
area. Use a stick if you need to remove debris from
the splitting area.

Pieces to be split with the machine in vertical position
should be cut as near to a 90° angle as possible.

Stand piece unsupported or leaned back against the log
carriage beam if possible.

• If you must support a piece, place your hand midway
down the outside surface - away from the beam - and
remove your hand as soon as the pieces is firmly held
between the wedge and the base plate.

• For best splitting results, place logs with the butt
(wider) end on the base plate.

• For horizontal splitting-

• Put one hand on top of log in the middle to keep it

steady until it's held firmly between wedge and

base plate - then get your hand out of there.

• For Vertical splitting -

• Stand piece unsupported or leaned back against the

log carriage beam if possible .

• If you must support a piece, place your hand

midway down the outside surface - away from the

beam - and take it away as soon as the piece is

firmly held between the wedge and the base plate.

• Activate control valve - push handle forward and hold.

• Keep holding valve handle down until split pieces fall
away or wedge reaches full extension, one or two
inches from base plate.

• Before starting return stroke, let hydraulic system
recover by moving valve handle to neutral position for

a moment.

• Make sure nothing will interfere with wedge while it
retracts.

• Press valve handle backward into locked position and
let go. Wedge returns by itself.

TIMBERWOLF Log Splitters

Operation Manual

• Valve handle stays in locked position until wedge is
fully retracted.

• To stop wedge -

• During forward stroke, release control handle .

• During return stroke, pull control handle
forward to release it from the locked position.

NOTE

Operate hydraulic control valve smoothly. Allow
a short pause when reversing directions, then
press lever firmly in direction you need to go.
Slamming valve lever in either direction makes
the system wear out faster.

• Clear split pieces from the operator zone frequently.
Allowing pieces to accumulate underfoot can be both

inconvenient and unsafe.
