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.

SEVERE INJURY OR PROPERTY DAMAGE.

In many instances, we have learned that the hydraulic relief valves of this equipment have

been reset, increasing the maximum pressures, and with it, the load the unit will lift before the

relief valve opens. In some instances, the consequences of increasing this setting have been

serious. The function of the relief valve is to provide a fuse action to protect the machine and

the operator from overloading. When overloaded, different portions of the machine can

become stressed to a level where parts fracture, possibly resulting in death, severe injury or

property damage. This is an extremely dangerous practice.This is an extremely dangerous practice.

This is an extremely dangerous practice.

Accordingly, you are advised that the settings of these valves are limited to the maximums

listed above..

. Pressure settings in excess of these levels render each and all Barko

warranties null and void and constitute an obvious misuse and abuse of our product.

SAFETY SUMMARY CONTINUED...

When you work on slopes there are several important points to consider:

Always use a seat belt when provided.

Speed of travel or working tools – higher speeds or sudden starts and stops can tend to make the machine

less stable

Terrain – soft ground, slopes, uneven surfaces (stumps, fallen trees and slash, rocks, valleys/rises, drop-offs or

ledges, overhangs), changing soil types, moisture, ice and snow affect the machine stability. Irregular terrain

must be traveled at slower speeds.

Direction of travel - Avoid operating the machine across the slope. When possible travel up or down slopes.

Place the heaviest end of the machine uphill and keep the load low to the ground. Turning uphill with an

articulated machine can increase the chance of tip-over.

Loads and shifting loads – Do not overload. Keep the load low and close to the machine. Contact with

overhead wires, trees, fallen trees or the ground can cause the load to shift unexpectedly and reduce stability.

Machine configuration – Will affect the weight distribution, the stability, the operating performance, and the

machine control on slopes.

Visibility – irregular, snow-covered or slash-covered terrain can reduce visibility in the path of the tracks or

wheels and to the surrounding area, the load, other vehicles, obstacles, and people.

Condition of the machine – Machine control and performance when operating on slopes may require special

machine maintenance or more frequent intervals. Fluid levels, track tension or tire inflation pressure can affect

machine control on slopes.

Do not operate a machine on a slope without proper training. Learn the stability limits of the machine by first

working on gentle slopes. Gain experience and improve skills over time by gradually increasing the angle of

slopes on which you are working. As operating conditions change make the appropriate decisions and

adjustments to maintain safe machine operation.

The following areas are the most common places for fires to start:

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.

- Stop engine & allow it to cool

- Read Engine Manual

- Use proper battery hook-up

procedures. See Electrical System
