BREAK IN PROCEDURE
KEEP ALL PERSONNEL CLEAR OF
M A CH I N E
DURING BREAK IN TO PREVENT I N J U R Y!!
Before using the log splitter, let the engine run for 30 minutes at half throttle. Work the
hydraulic cylinder out and in without splitting any wood.
SERVICE
INFORMATION
1. Check reservoir level using sight glass on the left side of the tank. If required, add to
reservoir tractor transmission / hydraulic fluid. For machine use in ambient temperatures
between +32°F (0°C) and +90°F (32°C) hydraulic fluid ISO 68 is recommended. If the
machine is operated at temperatures below +32°F (0°C) then hydraulic fluid ISO 46 is
recommended. Recheck the oil level after the log splitter has been run and oil has
been circulated through the hydraulic system. Routinely check the level thereafter.
DO NOT OVERFILL THE TANK.
2. Change the hydraulic oil filter after the first 50 hours of use. Change it after every 200
hours thereafter.
3. Add 1 quart of hydraulic oil to the reservoir with each oil filter change.
4. Check all hydraulic fittings for leaks and tighten if necessary.
5. The grease zerk on both swing arm pivot pins should be greased once a week or so,
depending upon use.
IMPORTANT: The engine is normally serviced prior to shipping. However, shipping
regulations may prohibit this. Check the levels and add oil and fuel as required before
starting. Service according to the engine manual before starting.
WARNING: Running the log splitter without hydraulic oil will cause serious damage to the
hydraulic pump. CHECK RESERVOIR LEVEL BEFORE STARTING THE MACHINE.

WIRING THE OPTIONAL LIGHTS
All parts required are provided (except the “truck plug”) in the optional lighting kit for
connecting to the towing vehicle.
Route the longest wire cable (4 stranded wires in a sheath) through the shielded cable run on
the right side of the frame, then through the tongue. The far left diagram is for tongues made
prior to the wiring hole in the bottom of the tube (middle diagram). Secure with the cable
clamp at the front of the tongue tube as shown in right diagram.
Route the shorter wire cables through the shielded cable runs on the bottom of the frame
(under the hydraulic fluid tank). The 36” cable goes to the right hand light, and the 41” cable
to the left hand light.
Using quick splices connect the stranded wires between the cable and each tail light. Match
the brown wires for the tail lamps. Green wires are for ground. The red wire for the RH turn
signal connects to the red wire in the cable. The red wire for the LH turn signal connects to
the yellow wire in the cable.
There are holes in the frame and light mounting brackets for anchoring wires with tie wraps.
Four pin connectors are typical for the three lighting functions (tail, turn, and brake) plus one
pin for the ground wire. Vehicle manufacturers have not standardized wiring colors. We
recommend that a circuit tester be used on the tow vehicle wiring to locate the correct wire for
each function. The wire that supplies 12 volt DC when switched on with the head lights of
the tow vehicle is for the tail lights.

TOWING INSTRUCTIONS
Be sure to obey all traffic laws and rules of the road while towing the Barreto log splitter. Never
exceed 45 miles per hour while towing. The towing vehicle should be in legal operating
condition. Refer to the following checklist before towing:
• The towing vehicle should have a 2" ball. Be sure it is in good repair and securely
fastened to the vehicle.
• Securely fasten the hitch to the ball by tightening the hitch nut.
• Attach the safety chain to the tongue as shown below.
• Cross the chains under the tongue to prevent the tongue dropping to the ground if the
splitter comes loose.
• Attach the safety chain to the towing vehicle in such a way that it cannot come off
accidentally.
• Check the hitch-to-ball connection after driving a few blocks and re-tighten if necessary.
• Allow only enough slack in the chains to permit proper turning of the vehicles. Do not let
chains drag on the ground or be drawn up too tight. Slack strength should hold the tongue
and coupler off the ground with the splitter loose.
• Swivel jack or stand should be parallel with tongue with pin in place.
• Be sure rail is locked in horizontal position when towing.
• Always exercise extreme caution and allow extra clearance while towing.
• If local law requires trailer lights, be sure they are in good repair and are in proper
working condition. Lights should be connected according to local and state laws.

OPERATING INSTRUCTIONS
1. READ SAFETY
INSTRUCTIONS BEFORE OPER A T I N G !
2. ALWAYS USE TWO HANDS WHEN OPERATING LOG SPLITTER!
THIS MACHINE IS DESIGNED TO BE OPERATED WITH TWO HANDS
AND FAILURE TO DO SO COULD RESULT IN VERY SERIOUS
INJURY, ESPECIALLY TO FINGERS!
3. Position the log splitter on dry level ground. Never use it on a slope or where there is not sure
footing. When you disconnect the log splitter from the tow vehicle, pull the detent ring pin
from the front leg or optional swivel jack. Rotate the leg or jack to the vertical position and
replace the pin.
4. Be sure engine oil and hydraulic oil are at proper levels before starting the engine.
5. Fill the fuel tank before you start while the engine is cold.
6. Turn the fuel line valve, choke, and engine switch to “on” position, then pull the starter
rope. Turn off the choke when appropriate. Refer to engine owner’s manual for details.
7. Always load and position the log with hands on sides of the log. Neve
r position with your
hands on the ends of the log. Always split wood in the direction of the grain, never across the
grain. Your log splitter has log holders. The log holders will cradle the wood to hold it on the
rail, allowing both hands to be free for operating the controls when splitting. The log holders
have two positions. The upper position provides the most support, designed to use when the
rail is horizontal. The low position is recommended when the rail is vertical.
8. Your log splitter has a standard safety lockout feature. Push down on either lockout lever with
one hand, then move the valve control lever with your other hand toward the log to split wood.
After splitting, move the lever away from the log. The valve detent will hold it in a retracting
operation, and will automatically release when the cylinder rod is fully retracted.
9. To use with the rail in the vertical position, disconnect from the towing vehicle. Pull the
horizontal position latch pin and rotate the rail using the handle provided. Make sure the
vertical latch pin locks the rail into place. Both latch pins are spring-loaded but can be held
unlocked by rotating the pin handle behind the stop. When you switch from horizontal to
vertical, the end of the rail hits the ground before the rail latches. Typically the whole
machine rolls back a few inches as the rail approaches vertical and the latch catches. If the
machine is attached to the towing vehicle it becomes very difficult if not impossible to latch
the rail to vertical.
