HBC SYSTEM Magnetic PDR Roll Tip kit
Instructions for use
1. Highlighting the dent with a line board
The line board highlights a dent or a high spot by deviation of its reflected lines.
The line board is optional.
To attach the line board first ensure the area is smooth and clean. Whilst pushing the rubber base flat against the point at which it will best reflect the dent, clip the movable suction cup handle down to lock the lineboard base to the panel. (First move the line board’s reflective board about until you get a clear reflection of parallel, black and white lines with a deviation of the pattern ie the dent, toward the centre of the reflection. A dent will be reflected as a widening of the lines and a high spot as a narrowing of the lines)
HIGHLIGHT THE DENT WITH THE LINEBOARD
SEPARATED/SWOLLEN LINES MEANS DENT (LOW)
SQUEEZED LINES MEANS HIGH SPOT
2. Select the bar, tip and extension combination that will allow the best access to the inside of the dented panel. Select tip size according to access available and panel gauge. 19mm Magnet PDR tip tool picks us trace better than 15mm in thicker gauge panels though due to size, will not access all desired areas. It may be necessary to remove trim, light fittings or gain access to a roof by dropping a corner of the headlining.
SELECT SUITABLE TOOL SHAPE AND EXTENSION COMBINATION
3. Use of the door bar
The black foam handled “U” shaped bar is designed to access door skins. Screw on the 15mm Magnet PDR tip tool, wind down window fully, separate glass from outer door skin by pushing the window wedge between them in the middle of the door, where flexibility is greatest. With wedge in place, introduce bar and tip as close to the wedge as possible with tip lying horizontal, ie at the tip’s narrowest dimension, to the opening made by the wedge.
It may be necessary to remove the exterior rubber or plastic horizontal window seal by sliding and or unclipping, to gain better access to the interior.
USE “U” SHAPED BAR FOR DOORS
4. Use of the two straight, red-handled bars. These are designed for panels such as wings, roofs, bonnets and bootlids.
USE STRAIGHT BARS FOR OTHER AREAS
5. Leverage points
Once the tool has been introduced and is in the dent area locate a suitable panel hole in which to hang the “S” hook so that the bar with “O” ring slid over can be hung on the “S” hook to create a leverage point when pushing the bar in the dent area.
It is not always possible to locate a suitable place from which to hang the “S” hook, in which case lever against any part of the surrounding body work which is strong enough, first protecting paintwork etc with suitable padding.
LOCATE LEVERAGE POINT FROM WHICH TO HANG “S” HOOK
6. Surface trace pick up.
Once bar is adequately levered (in the case of the door bar leverage is against the glass, so no further leverage point is necessary, neither are “S” hooks nor “O” rings), offer a surface trace ball to the dented area, moving it around with the fingertips until it is picked up by the tip. Once picked up, slowly slide the tip around by moving the handle until you are comfortable with the movements.
INTRODUCE BAR TO INSIDE OF PANEL IN DENTED AREA
OFFER SURFACE TRACE TO DENTED ARE UNTIL PICKED UP BY TIP
7. Pushing out a typical round dent/ding.
The dent should be pushed out slowly and with minimum pressure to avoid pushing the panel high (see tapping down), and risking the possibility of cracking the paint. Push down on the handle, causing downward pressure on the “S” hook and “O” ring, an upward pressure on the tip against the dent. The general rule is to imagine the dent is a clock face and, starting at one number, follow the order of numbers pushing once on each number until the circle has been completed. You should now see that the dent has decreased in size. It is important to keep the dent regular by maintaining the same pressure for each push and keeping to the circular pattern.
Next move in toward the centre slightly, and repeat. Continue in decreasing concentric circles until the dent has dissappeared or you are left with just the centre. If left with the centre, depending o the depth you may need to push the centre out high before tapping down to finish.
IMAGINE DENT AS A CLOCK FACE. FOLLOW SEQUENCE OF NUMBERS UNTIL CIRCLE IS COMPLETED.
MOVE SLIGHTLY TOWARD CENTRE AND REPEAT.
PUSH SLOWLY AND EVENLY WITH MINIMUM PRESSURE
8. Tapping down.
If you push too hard or need to lift the centre pit of a deep dent, the panel’s metal will stand proud and you will have to tap down,
Using the nylon punch and hammer provided, and following the pinched lines on the lineboard , gradually tap down the highs created.
It is important that you tap down a high as soon as you create it otherwise irregularity will occur and confuse the dent’s reflection, making it much harder to read and so remove.
IF YOU GO HIGH, TAP DOWN BEFORE CONTINUING
9. Flatting and polishing.
After removing a dent the surface may appear “pock marked” from numerous pushes.
These can me removed by flatting with 2000 wet and dry, before polishing.
FLATTING AND POLISHING CAN REMOVE MINOR SURFACE IRREGULARITIES
10. Maintain Magnet PDR tip tool kit clean and lightly lubricated with oil, grease or vaseline.
MAINTAIN MAGNET ROLLER TIPS CLEAN AND LIGHLY LUBRICATED
