SERVICE

Good maintenance practice keeps the drill on the job and increases its service life.

The most important maintenance practice is to keep the hydraulic fl uid clean at all times. Contaminated hydraulic

fluid causes rapid wear and/or failure of internal parts.

Follow the procedure contained in the HYDRAULIC SYS- TEM REQUIREMENTS section of the manual to ensure peak performance from the tool.

Never disassemble the tool unless proper troubleshooting procedures have isolated the problem to an internal part. Disassemble it only to the extent necessary to replace the defective part. KEEP CONTAMINANTS SUCH AS DIRT AND GRIT AWAY FROM INTERNAL PARTS AT ALL TIMES.

Always determine and correct the cause of the problem prior to assembly. Further wear and tool failure can result if the original cause is not corrected.

HAMMER DRILL DISASSEMBLY

4.Remove the two capscrews (3/8 hex socket) and two side rods. Remove handle assembly to expose ON/OFF valve spool and accumulator diaphragm. Remove the mo- tor assembly by tapping the top of the motor fl ange with a plastic or rubber hammer.

5.Remove the accumulator valve block by tapping on its underside with a plastic or rubber hammer. Tap on alter- nate sides to ensure that the valve block comes off straight without binding.

6.Remove piston from the fl ow sleeve assembly.

7.Remove the accumulator diaphragm and ON/OFF valve from accumulator valve block, taking care not to damage the valve stem. The valve, bushing and associated seals will come out as an assembly. Turn the valve block upside down to remove valve spring.

8.Clamp the accumulator valve body in a bench vise with the IN/OUT ports facing up.

IMPORTANT

Do not overtighten the vise and distort the block.

PRIOR TO DISASSEMBLY

Clean exterior of tool.

Obtain Seal Kit (Part Number 05839). Replace all seals ex- posed during disassembly. Note orientation of seals before removing them. Install new seals in the same way.

DISASSEMBLY

1.Secure the drill in a bench vise with the “IN” and “OUT” ports up, clamping on the fl ow sleeve tube between the side rods. Soft vise jaws are recommended.

2.Remove the pigtail hose assemblies.

Note:

The drill is full of oil and will drip from the ports when the hoses are removed.

3. Remove the charge valve cap from the top of the handle.

WARNING

Discharge accumulator.

9.Remove the porting block with a 3/8-16 thread slide hammer or Tamper Sleeve Tool (part number 01120).

FLOW SLEEVE DISASSEMBLY

1.Remove the piston if not previously removed.

2.Place the fl ow sleeve assembly, automatic valve body down, on Flow Sleeve Removal Tool (part number 04919), which in turn is placed on Flow Sleeve Removal Tube (part number 04910).

3.With an arbor press and using an aluminum disc to pro- tect the fl ow sleeve, push on the fl ow sleeve to remove the automatic valve body.

IMPORTANT

Use a rag in the bottom of the removal tube to protect the automatic valve body when it drops out.

4.The automatic valve, four 1/4 x 1-1/2 inch push pins from the fl ow sleeve and two 3/16 x 1-1/4 inch push pins from the automatic valve body will come out.
