SAFETY PRECAUTIONS

Tool operators and maintenance personnel must always

comply with the safety precautions given in this manual

and on the stickers and tags attached to the tool and

hose.

·

These safety precautions are given for your safety.

Review them carefully before operating the tool and · before performing general maintenance or repairs.

Supervising personnel should develop additional precautions relating to the specific work area and local safety regulations. If so, place the added precautions in · the space provided in this manual.

The VF80 Hydraulic Vent Fan will provide safe and · dependable service if operated in accordance with the

instructions given in this manual. Read and understand this manual and any stickers and tags attached to the ·

tool and hoses before operation. Failure to do so could

result in personal injury or equipment damage.

·

· Operator must start in a work area without bystanders. The operator must be familiar with all prohibited work areas such as excessive slopes and dangerous terrain conditions.
· Establish a training program for all operators to ensure safe operation.
· Do not operate the tool unless thoroughly trained or under the supervision of an instructor.
· Always wear safety equipment such as goggles, ear, head protection, and safety shoes at all times when operating the tool. Never wear loose clothing that can get entangled in the working parts of the tool.
· Do not inspect or clean the tool while the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury.
· Supply hoses must have a minimum working pressure rating of 2500 psi/175 bar.
· Be sure all hose connections are tight.
· The hydraulic circuit control valve must be in the OFF position when coupling or uncoupling the tool. Wipe all couplers clean before connecting. Use only lint-free cloths. Failure to do so may result in damage to the quick couplers and cause overheating of the hydraulic system.
· Do not operate the tool at oil temperatures above

140 °F/60 °C. Operation at higher oil temperatures can cause operator discomfort and may damage the tool.
Do not operate a damaged, improperly adjusted, or incompletely assembled tool.
To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by authorized and properly trained personnel.
Do not exceed the rated limits of the tool or use the tool for applications beyond its design capacity.
Always keep critical tool markings, such as labels and warning stickers legible.
Always replace parts with replacement parts recommended by STANLEY.
Warning: Use of this tool on certain materials during demolition could generate dust potentially containing a variety of hazardous substances such as asbestos, silica or lead. Inhalation of dust containing these or other hazardous substances could result in serious injury, cancer or death. Protect yourself and those around you. Research and understand the materials you are cutting. Follow correct safety procedures and comply with all applicable national, state or provisional health and safety regulations relating to them, including, if appropriate arranging for the safe disposal of the materials by a qualified person.

HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with STANLEY hydraulic tools. They are:
Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified nonconductive is the only hose authorized for use near electrical conductors. Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near electrical conductors.
Fabric-braided (not certified or labeled non-conductive) — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This hose is not certified non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from STANLEY. DO NOT REMOVE THESE TAGS.
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be obtained from your STANLEY Distributor.

HOSE RECOMMENDATIONS
8 VF80 User Manual

Tool to Hydraulic Circuit Hose Recommendations
The chart to the right shows recommended minimum hose diameters for various hose lengths based on gallons per minute (GPM)/liters per minute (LPM). These recommendations are intended to keep return line pressure (back pressure) to a minimum acceptable level to ensure maximum tool performance.
This chart is intended to be used for hydraulic tool applications only based on STANLEY tool operating requirements and should not be used for any other applications.
All hydraulic hose must have at least a rated minimum working pressure equal to the maximum hydraulic system relief valve setting.
All hydraulic hose must meet or exceed specifications as set forth by SAE J517.

OPERATION
PRE-OPERATION PROCEDURES
PREPARATION FOR INITIAL USE
The tool, as shipped, has no special unpacking or assembly requirements prior to usage. Inspection to assure the tool was not damaged in shipping and does not contain packing debris is all that is required.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 412 GPM/1545 LPM at 5002000 psi/35 140 bar.
2. Make certain the hydraulic power source is equipped with a relief valve set to open at 2250 psi/155 bar maximum.
CHECK TOOL
1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly can result in damage to the tool or personal injury.
2. There should be no signs of leaks. 3. The tool should be clean, with all fittings and
fasteners tight.
OPERATING PROCEDURES
1. Observe all safety precautions. 2. Place the vent fan in the area to be ventilated. 3. Start the vent fan.
COLD WEATHER OPERATION
If the tool is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.
STORAGE
1. Disconnect the tool from the hydraulic power source. 2. Wipe clean and store in a clean, dry place.

TROUBLESHOOTING
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When diagnosing faults in operation of the tool, always make sure the hydraulic power source is supplying the correct hydraulic flow and pressure as listed in the table. Use a flow meter known to be accurate. Check the flow with the hydraulic fluid temperature at least 80 °F/27 °C.

SYMPTOM Tool does not run.

CAUSE Power unit not functioning.
