INTRODUCTIONINTRODUCTION

INTRODUCTION

Your Barko Mulcher has been designed and manufactured with high quality materials and care in workmanship. This

manual is intended as a permanent reference to aid professional operator's in their work, and should be available for

use at any time. If the machine is not equipped with this manual, ask your supervisor to obtain one for you.

Understand the correct servicing procedures before servicing the machine. It is important to know the correct

operating and servicing procedures of the Mulcher and all safety precautions to prevent the possibility of property

damage and/or personal injury or death.

As a professional, trained operator, you are responsible for safety, both your own and that of your co-workers. Your

knowledge and use of all safety practices and correct servicing procedures in this manual, and your good judgement,

can be a major factor in preventing some of the thousands of injuries and deaths caused by industrial accidents each

year.

A professional operator should also be familiar with the information contained in other applicable sources such as

American National Standards, SAE, OSHA, etc.

ADDITIONAL INFORMATION:

Logging Safety Resource Guide (APA, 95-A-1) is available from the American Pulpwood Association. This guide lists

sources of videotapes, slide programs, movies, and publications on various aspects of logging safety.

FIRE PREVENTIONFIRE PREVENTION

FIRE PREVENTION

This machine has several components which are at high temperatures under normal operating conditions, such as

engine, exhaust system, brake system and transmission. Also, electrical system (battery, electrical connectors, etc.)

can be a source of arcs or sparks if damaged or incorrectly maintained.

Excessive debris will increase the condition for a fire hazard. Flammable debris (twigs, leaves, straw, rags, etc.) must

be removed on a daily basison a daily basis

on a daily basison a daily basis

on a daily basis or more often if necessary from areas such as the engine, exhaust, battery, electrical

connectors, parking brake components, transmission area and belly pan, drive line, fuel, hydraulic and brake systems.

Clean machine often. Periodic high pressure washing of machine is suggested, especially if flammable liquid spills

have occurred.

The following list provides data which

will help to prevent fires.

- Do not use machine in areas with

explosive dust or gases. These

elements can be ignited by arcs,

sparks, hot components or fumes.

- Inspect cab, engine

compartment, and engine cooling

system every day. Clean if needed

to prevent overheating. Remove all

flammable material (rags, debris,

fluid spills, etc.)

- Inspect electrical system

for damage daily. Keep battery

terminals clean & tight. Replace or

repair any damaged part.

- Daily, inspect all fuel and

hydraulic oil tubes, hoses, and fittings

for damage and leakage. Tighten or

replace as needed. Always clean

fluid spills.

- Allow machine to cool down by

idling engine for a while before

shutdown. Many engine and

transmission fires start after shut-

down. This waiting time can be used

to inspect machine and perform

certain maintenance procedures.

- Keep fire extinguisher, water

hose connected to water tank, and

first aid kit where easily reached in

case of fire and keep these items

properly maintained.

- Operating personnel should

be instructed on what to do in case of

fire and be required to demonstrate

use of fire extinguisher and fire

suppression equipment.

- Any portable extinguisher or

fire suppression system carried on

machine that has been used, must be

recharged or replaced before

machine resumes operating.

Extinguisher manufacturers

recommended service interval

should be followed.

- Do not use ether or starting

fluids on diesel engines with glow

plugs. These starting aids can

explode and injure bystanders.

- Before doing welding of any

kind, clean machine and disconnect

battery cables. Cover rubber hoses,

battery, & other flammable parts.

Never ground arc welder or electrical

accessories through machine

components as arcing may occur

causing bearing damage. Keep fire

extinguisher nearby.

SAFETY WHILE SERVICINGSAFETY WHILE SERVICING

SAFETY WHILE SERVICING

The following maintenance section gives suggested guidelines for operational maintenance on your machine. In

severe conditions (extreme dust, heat, cold, humidity, etc.) you will need to service your machine more often. Your

experience will dictate a more severe servicing program.

Safety while servicing your machine is your responsibility. Only qualified and authorized personnel should be

permitted to maintain, repair, adjust and inspect the machine.

Read and understand the warnings and safety precautions in the Safety Summary and elsewhere in this manual

before doing any service on the machine. The following precautions should be used as a reminder to safe servicing.

Preventive maintenance is really just a simple matter of common sense. If you keep any piece of mechanical

equipment clean and properly lubricated, and promptly replace any worn or damaged parts, you are going to "prevent"

deterioration and promote long life and safe, productive service. The only other requisite to such a program is the

regular scheduling of such maintenance.

Obviously, when you are operating under severe job conditions, such as a dusty job site, in extreme heat or cold, a long

operating day, or extremely heavy loads, the recommended intervals in the schedule should be shortened.

The suggested schedule on the following page is designed to be just a reminder of what should be done. For detailed

instructions on each item, consult the Table of Contents for where each is located in this manual.

AFTER THE FIRST 50 HOURS OF OPERATION OF A NEW MACHINEAFTER THE FIRST 50 HOURS OF OPERATION OF A NEW MACHINE

AFTER THE FIRST 50 HOURS OF OPERATION OF A NEW MACHINE

A new machine needs a special maintenance procedure after the first 50 hours of operation.

1. Do a complete inspection of the machine. Rectify any problems, replace any damaged parts.

2. Check torque of bolts and nuts (retorque if necessary):

3. Change all filter elements.

4. Change hydraulic oil in hydraulic oil reservoir.

Resume the normal maintenance intervals after this. See the Service Schedule for more information.
