MAINTENANCE FOR THE

MODEL 210B SRA

SAFETY PRECAUTIONS FOR THE

MODEL 210B SRA

System Under Pressure: Shut off air supply and disconnect air

hose before disassembling or disconnecting parts.

Flying Debris: During boring, chips may be ejected. Stay behind

control panel and wear safety glasses to prevent eye injury.

Pinch Points: Keep hand clear of carriage assembly. Hands or

fingers caught between carriage and frame may be seriously injured.

Moving Parts: When moving drill unit, use carriage lock to

prevent assembly from sliding onto hands or fingers.

Heavy Load: Use handles to reposition the drill unit. Weight of

the drill unit may cause back strain if improperly lifted.

SAFETY PRECAUTIONS FOR THE

MODEL 210B SRA (continued)

Loud Noise: Wear ear protection to prevent eardrum damage

from air compressor.

Dust: Wear a dust protection mask to protect from concrete dust.

High Pressure: High pressure from the air compressor can

damage the drill, and can void the warranty.

Lifting The Drill Unit: when using a lifting device to pick up the

drill unit, use a strap or chain which is rated for the proper weight,

and attach to the lifting bale on the drill unit. Be sure carriage lock is

in place.

MAINTENANCE FOR THE

MODEL 210B SRA

• Check bolts daily for tightness.

Due to the extreme amount of

vibration, bolts will loosen. It is

important keep nuts and bolts

tight.

EXCEPTION: The two ½” x 4”

bolts that connect the upper drill

bracket and the lower drill bracket

can be too tight. There should be

a gap between the two brackets.

When tightening these bolts, put a

drill bit in the chuck and turn it as

you tighten the nuts. At some

point, it will “catch” or “drag” while

turning the bit. This means the

bracket is too tight. Loosen the

nuts until you can turn the bit

freely, the tighten the lock nuts.

MAINTENANCE FOR THE

MODEL 210B SRA

• Check all nuts and bolts around

the carriage assembly daily.

Tighten as needed.

•Allowing bolts or connections to

work loose may disqualify any

warranty on these parts.

MAINTENANCE FOR THE

MODEL 210B SRA

• Check all nuts and bolts on the

rock drill daily.

IMPORTANT: If a nut on one of

the thru bolts gets loose, or if a nut

on one of the trunnion bolts gets

loose, it will cause the other one

that is tight to break.

MAINTENANCE FOR THE

MODEL 210B SRA

• Check all stop rods and stop rod

nuts daily and keep them tight.

MAINTENANCE FOR THE

MODEL 210B SRA

DO NOT REMOVE CAP

UNDER PRESSURE!

(to remove pressure from

system, have air supply disconnected

from drill unit, and open the Power

lever to the “On” position)

• Fill the oil reservoir daily with

the recommended rock drill oil

(do not use oil that is too light,

such as Marvel Mystery Oil,

automatic transmission fluid,

air tool oil, etc.). Running the

oil tank dry can cause damage

the drill motor.

RECOMMENDED SPECIFICATIONS FOR ROCK DRILL

LUBRICANT

The use of synthetic oils is NOT RECOMMENDED due to possible damage to seals, “O” rings, hoses, blades, and polycarbonate oiler/filter bowls. Use

only a non-detergent, Class 2, pneumatic lubricating oil (viscosity 100-200 S.S.U. @ 100° F and minimum aniline point of 200°F); which contains no

synthetic additives; and which is compatible with Buna-N, Neoprene, Urethane, Silicone, and Hytrel components.

Consistency shall be such that the oil will adhere readily to metallic surfaces under extreme pressure conditions that exist in a rock drill.

(a) Where lower than normal viscosity oil is used at extreme low temperature, 350°F flash point permissible.

(b) 1200+ desired where moisture is a major factor. Operator must compensate for foaming when filling the lubricator.

(d) Desired values, not minimum. Rock drill oils must have appreciably greater load carrying ability than straight mineral oils of like viscosity. High film

strength is required by the heavy rotational loads present in drilling conditions. Additives which impart extreme pressure characteristics to the oil must

be non-corrosive to the drill mechanism.
