SAFETY

The SK58 Hydraulic Sinker Drill 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.

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 on page 3.

SAFETY

GENERAL SAFETY PRECAUTIONS

• 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 and head protection, and safety shoes at all times when operating the tool.

• Know the location of buried or covered underground utilities before begining any work.

• Do not inspect or clean the tool while the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury.

• Always connect hoses to the tool hose couplers before energizing the hydraulic power source. Be sure all hose connections are tight.

• Do not operate the tool at oil temperatures above 140°F/60°C. Operation at higher oil temperatures can cause higher than normal temperatures at the tool which can result in operator discomfort.

• Do not operate a damaged, improperly adjusted, or incompletely assembled breaker.

• Do not weld, cut with an acetylene torch, or hard face the drill bit.

• To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by authorized and properly trained personnel.

SAFETY Continued . . .

• Always replace parts with replacement parts recommended by Stanley Hydraulic T ools.

• Check fastener tightness often and before each use daily.

SAFETY SYMBOLS

Safety symbols are used to emphasize all operator, maintenance and repair actions which, if not strictly followed, could result in a life-threatening situation, bodily injury or damage to equipment.

This safety symbol may appear on the tool. It is used to alert the operator of an action that could place him/her or others in a life threatening situation.

This safety symbol appears in these instructions to identify an action that could cause bodily injury to the operator or other personnel.

This safety symbol appears in these instructions to identify an action or condition that could result in damage to the tool or other equipment.

Always observe safety symbols. They are included for your safety and for the protection of the tool.

LOCAL SAFETY REGULATIONS

Enter any local safety regulations here. Keep these instructions in an area accessible to the operator and maintenance personnel.

HYDRAULIC SYSTEM REQUIREMENTS

• The hydraulic system should provide a flow of 7-9 gpm/26-34 lpm at an operating pressure of 2000 psi/140 bar. Recommended relief valve setting is 2100-2250 psi/145-155 bar.

• The system should have no more than 250 psi/17 bar backpressure measured at the tool end of the operating hoses. The system conditions for measurement are at maximum fluid viscosity of 400 ssu/82 centistokes (minimum operating temperatures).

• The hydraulic system should have enough heat rejection capacity to limit the maximum oil temperature to 140°F/60°C at the maximum expected ambient temperature.

• The hydraulic system should have a minimum of 25 micron filtration. Stanley recommends using filter

The SK58 Sinker Drill is designed to be used to drill holes in rock such as blast holes.

A rock bit containing carbides is attached to drill steel which is inserted into the tool. The tool incorporates a reciprocating piston and a varible speed hydraulic motor. During the drilling process, the piston hammers on the drill steel and the hydraulic motor rotates the drill steel. It is the pounding and rotating motion of the rock bit that causes the rock to fracture into small cuttings.

It is necessary to extract the rock shavings during the drilling process. If the rock shavings are not extracted, the rock bit will sit on top of the shavings, which in turn, will prevent the rock bit from penetrating into the rock.

On SK58110, SK58120, and SK58310 models, air is introduced into the drill steel via a valve in the tool to blow the rock cuttings out of the hole. On the SK58130 model, water is used to flush out the rock cuttings.

elements sized for a flow of at least 30 gpm/114 lpm for cold temperature startup and maximum dirt holding capacity.

• The hydraulic fluid used should have a viscosity between 100 and 400 ssu/20 and 82 centistokes at the maximum and minimum expected operating temperatures. Petroleum base hydraulic fluids with antiwear properties and a viscosity index over 140 ssu/28 centistokes will meet the recommended requirements over a wide range of operating temperatures.

• The recommended hose size is .500 inch/12 mm I.D. up to 50 ft/15 m long and .625 inch/16 mm I.D. minimum up to 100 ft/30 m long.

• Quick disconnect couplings must conform to NFPA T3.20,15/EHTMA specifications.

PRINCIPLE OF OPERATION

factor for the particular application. Incorrect rotation speed and/or inadequate extraction of the rock cuttings will significantly reduce drilling effectiveness and result in substantially increased drilling time.

The tool can drill up to a 3 in./75 mm hole up to 20 feet/ 6 meters deep in rock. The tool has been used for other applications such as dowel drilling and gas leak detection.

Because the tool has been specifically designed to be operated by an individual, it should never be mounted to and operated from a machine such as a drilling rig or small excavator. If a requirement exists to machine mount the tool, the application must first be approved by Stanley Engineering. Failure to obtain this approval can result in tool failure and void the warranty.

See the "OPERATING INSTRUCTIONS" section of this manual for specific operating instructions.

The air requirements for effective drilling are 30 cfm at 120 psi. The air supply is furnished by an air compressor.

SK58 Sinker Drills are designed to be operated and controlled by one individual. The rotation speed of the drill steel and amount of air introduced into the drill steel is adjusted by the operator based on an experience
