SAFETY OBSERVE SAFETY SIGNS AND MESSAGES THINK SAFETY: Safety is a combination of operator common sense and alertness at all times when the machine is being operated or serviced. CAUTION: This message is used for general reminders of good safety practices or to direct attention to unsafe prac- tices.
SAFETY WEAR PROTECTIVE CLOTHING Wear close-fitting clothing and safety equipment appro- priate to the job. Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. Prolonged exposure to loud noise can cause impaired or loss of hearing.
SAFETY SAFETY STICKERS READ SAFETY SIGNS CAREFULLY Carefully read and follow all safety signs. Danger signs identify the most serious hazards. Keep safety signs in good condition. Replace any missing or damaged safety signs. Signs are attached to machine near specific hazard areas.
All personnel must observe these guidelines when working with the equipment. This special safety manual has been prepared for all owners and operators of Morbark hand-fed brush and tree chippers. SAFETY IS NO ACCIDENT.

SAFETY OPERATION Before anyone starts up a brush chipper, they should know this: ANY MACHINE THAT CAN PULL IN A WHOLE TREE AND CHIP IT IN LESS THAN A MINUTE IS DANGEROUS IF THE OPERATOR DOES NOT FOLLOW PROPER SAFETY PROCEDURES.
Page 15
SAFETY OPERATION If the chipper is attached to a truck or van, make certain the hitch is secure and the safety chains are properly attached. If the chipper is not attached to a vehicle, the tongue should be blocked and wheel chocks should be placed under both wheels to keep the chipper from moving.

SAFETY OPERATION Again, the single most important chipper safety rule is NEVER BREAK THE PLANE OF THE INFEED CHUTE WITH YOUR HANDS, AND NEVER, FOR ANY REASON, ATTEMPT TO KICK BRUSH IN WITH YOUR FEET! To safely feed short material into your chipper, place the feed system in the neutral position, lay the short material on top of longer material, and engage the feed system.
Page 17
SAFETY OPERATION At least two people should be on the job site at all times. No one should ever operate the chipper alone. It is the operator's responsibility to ensure that other workers or bystanders are kept away from the path of discharged chips. Be prepared in case of an accident.

SAFETY OPERATION When refueling the chipper, always be certain there is no open flame or source of a spark in the vicinity of the machine. Always remove the ignition key when the machine is left unattended for any reason. No one should ever operate the chipper when under the influence of drugs, alcohol or pre- scription medications which could in any way affect the operator's performance and concen-...
Safety is just too important to be taken lightly. With proper information and commit- ment to safety every day, your Morbark hand- fed chipper will give you years of reliable, safe service. SAFETY HINTS 1.
SAFETY OPERATION NEW ENGINE BREAK-IN Proper break-in will lead to trouble free operation and increased engine life. The factory test given to a new engine is not sufficient to establish the polished bearing surfaces which are so necessary for good performance and long life.
SAFETY OPERATION BRUSH PREPARATION Inspecting and organizing the brush prior to chipping will allow the job to be performed more efficiently and provide added safety in performing the job by minimizing the danger of foreign material, vines, etc from entering the chipper. Pre-trimming and proper de-limbing will allow the brush to be drawn easily through the chipper.

SAFETY OPERATION BRUSH PREPARATION CON’T Know the limitations of your chipper. Never attempt to feed material too large for your chipper. Always pre-cut large crotches to ensure adequate clearance through the transition area. When preparing large material for feeding, properly trimming the crotches will greatly reduce the amount of downtime from clearing jammed materials.
SAFETY OPERATION INSPECTING CHIPPER KNIVES CAUTION: BEFORE INSPECTING KNIVES, REMOVE IGNITION KEY AND LOCK OUT ENGINE PANEL. CAUTION: MAKE SURE THE CHIPPER DRUM HAS COME TO A COMPLETE STOP. Remove chipper hood lock pin and open the hood. Turn drum by hand until first knife is accessible.
SAFETY OPERATION PTO HOOKUP CAUTION: MAKE SURE THE AREA BEHIND YOUR TRAC- TOR IS CLEAR BEFORE BACKING UP TO CHIPPER. Align tractor 3-way hitch arms to the mounting brackets on the chipper. Pin and secure chipper to tractor hitch arms. Slide the PTO driveshaft onto the splined shaft of your tractor.
SAFETY OPERATION MACHINE WARM-UP NOTE: Most engines include a safety shutdown system. This system will shut down if coolant tem- perature is too high or oil pressure is too low. If service is required, please contact your nearest authorized dealer. 1.
SAFETY OPERATION DISENGAGING CUTTER DRUM Disengage the hydraulic feed sys- tem by moving the feed control bar to the NEUTRAL or center position. Push the throttle control in to reduce engine speed to idle. When the engine and cutter drum reach idle speed, disengage clutch.
SAFETY OPERATION FEEDING BRUSH TO THE CHIPPER Keep the working area clear of limbs and debris. Tripping or entanglement hazards CAN cause the operator to be dragged into the chipper, causing serious injury or death. Do not throw clean up sweepings into the cutter mechanism. Foreign material such as stones, wire or metal CAN cause blade failure, resulting in serious personal injury.
ENGINE CONTROLS 1. PERMISSIVE START BUTTON - Used 6. TACHOMETER\SPEED SWITCH - in conjunction with the key switch to start The tachometer measures the revolutions engine. per minute of the power unit. Idle Speed - Set by manufacturer. 2. KEY SWITCH - Used in conjunction with Max.
FEED CONTROLS The feed rollers are controlled by pushing or pulling the feed control bar, which is located on the top and both sides of the feed chute. The 3 (Three) control positions are: FEED - Pulls material into the chipper cutting zone. NEUTRAL - Stops movement of the feed rollers.
ROUTINE MAINTENANCE Safety and daily maintenance are the two most important things to remember when operating machin- ery. A small amount of daily maintenance will make the weekly or monthly maintenance much easier and less expensive. While maintaining your brush chipper, please follow the safety guidelines which are written in bold print.
ROUTINE MAINTENANCE CHANGING CHIPPER KNIVES CAUTION: BEFORE CHANGING KNIVES, ALWAYS REMOVE IGNTION KEYS AND LOCK OUT ENGINE PANEL. CAUTION: MAKE SURE THE CHIPPER DRUM HAS COME TO A COMPLETE STOP. 1. Remove chipper hood lock pin and open the hood. 2.
ROUTINE MAINTENANCE INSPECTING AND ADJUSTING THE KNIFE ANVIL CLEARANCE The anvil should be adjusted to a minimum of .045 and a maximum of .080 from the cutting edge of the highest chipper knife. To inspect and adjust the knife anvil clearance, follow these steps: 1.
ROUTINE MAINTENANCE WHAT YOU SHOULD KNOW ABOUT CHIPPER KNIFE MAINTENANCE Properly maintained chipper knifes will give you longer service. When knives are badly abused you can usually only expect minimal sharpenings before the knife is worn out. With proper maintenance and frequent knife changes, you can get more knife sharpenings per edge.

ROUTINE MAINTENANCE Use proper hardware for mounting knife to holder. Torque mounting bolts properly to eliminate wood packing and possible knife breakage. Bevel of knife must exceed mounting bolts for clearance when chipping. Proper anvil clearance, sharp anvils and knives should be maintained for quality chips. A good, efficient cut can eliminate plugging problems and undue stress on the chipper.
