AJUSTES

INSTALANDO UMA CORREIA

DE LIXAMENTO

Quando uma correia de lixamento nova for instalada proceda da seguinte maneira:

1. Para modelos com 18”, deslize a Capa para trás em

direção ao punho do Lixador até libertá–la. Pode ser necessário uma leve pancada na extremidade frontal da capa para livrá–lo dos seus pontos de travamento.

2. Comprima o Disco Falso e retire a correia velha para fora da Camisa de comando. Alivie a pressão no Disco Falso e remova a correia.

3. Posicione a correia nova no Disco Falso.

4. Comprima o Disco Falso com a correia e coloque a extremidade oposta da correia na Camisa de Comando ao redor do Tampo do Fuso. Alivie a pressão no Disco Falso.

5. Para modelos com 18”, alinhe a Capa com o Protector e deslize para frente em direção do Disco Falso até que ele prenda na posição e lá permaneça.

6. Opere o Lixador com velocidade baixa para verificar se a nova Correia está propriamente colocada. Se a Correia não correr no trilho de maneira apropriada, realinhe o Olhal ao apertar ou afrouxar um ou ambos Parafusos de Montagem do Olhal.

DISASSEMBLY

General Instructions

1. Do not disassemble the tool any further than necessary to replace or repair damaged parts.

2. When grasping a tool or part in a vise, always use the surface of the part or tool and help prevent distortion. This is particularly true of threaded members and housings.

3. Do not remove any part which is a press fit in or on a subassembly unless the removal of that part is necessary for repairs or replacement.

4. Do not disassemble the tool unless you have a complete set of new gaskets and O–rings for replacement.

5. Do not press any needle bearing from a part unless you have a new needle bearing on hand for installation. Needle bearings are always damaged during the removal process.

Disassembly of the Sanding Arm

1. For 18” models, slide the Cover (35B) rearward toward the handle of the Sander until it is free. It may require a light rap on the front edge of the Cover to disengage it from its locking points.

2. Using the Guard Clamp Screw Wrench (50), loosen the Guard Clamp Screw (35) and remove the Guard (34) and assembled sanding arm from the Angle Housing (22).

3. Using a screwdriver, remove the two Clevis Mounting Screws (37) and separate the Clevis (36) from the Guard.

4. For 12” x 1/2” and 18” x 1/2” models, use a screwdriver, to remove the two Belt Plate Retaining Screws (40), two Belt Plate Spacers (41) and the Belt Plate (39).

5. If the Belt Pad (38) must be replaced, peel the Pad from the side of the Clevis or Yoke (42) and scrape the surfaces clean.

6. To separate the Yoke from the Clevis, press the Yoke Retaining Pin (44) out of the Yoke and Clevis with an arbor press.

Be careful not to allow the compression of the Yoke Spring (43) to expel the Yoke or Clevis in an unsafe manner when the pressing plug is withdrawn from the Yoke.

7. Press the Idler Wheel Shaft (49) out of the Yoke and Idler Wheel (45).

8. The Idler Wheel contains an Idler Wheel Bearing (47) at each end. Simultaneously press both Bearings out of the Wheel.

Disassembly of the Angle Head

1. Grasp the tool in leather–covered or copper–covered vise jaws with the Spindle Cap (32) upward. Using the Collet Body Wrench (50) on the flats of the Arbor (31), unscrew the Spindle Cap. If the Drive Sleeve (33) needs replacement, cut the old one from the Spindle Cap.

2. Using the Arbor Bearing Cap Wrench (53), unscrew and remove the Arbor Bearing Cap (30). This is a left–hand thread. Rotate the Cap Wrench clockwise to remove the Cap.

3. Using the Clamp Nut Wrench (52), loosen the Clamp Nut (24) and pull the Angle Housing Assembly (22) away from the Motor Housing (5). This is a left–hand thread. Rotate the Nut Wrench clockwise to loosen the Nut.

Do not allow the Angle Head to rotate when separating it from the Motor. Components may fall from the Angle Head.

4. Grasp the Arbor and pull the assembled Arbor out of the Angle Head. If the Wick (27) needs replacement, pull it out of the Angle Housing.

5. If the Upper Arbor Bearing (26) needs replacement, place the Angle Head on the table of an arbor press, arbor end down, and press the Bearing out of the Angle Head.
