Important Safety Instructions

WARNING: Read and understand all instructions. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

• KEEP GUARDS IN PLACE and in working order.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that

keys and adjusting wrenches are removed from tool before turning it on.

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

• DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet

locations, or expose them to rain. Keep work area well lighted.

• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work

area.

• MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing

starter keys.

• DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was

designed.

• USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not

designed.

• USE PROPER EXTENSION CORD. Make sure your extension cord is in good

condition. When using and extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Additional Safety Rules for Chop Saw

• Always wear proper eye and respiratory protection.

• Before using, inspect the cutting wheel for cracks or flaws. If such a crack or flaw is evident, discard the wheel. The wheel should also be inspected whenever you think the tool may have been dropped. Flaws may cause wheel breakage.

• When starting the tool with a new or replacement wheel or if you are unsure of the condition of the wheel, hold the tool in a well protected area and let it run for one minute. If the wheel has an undetected crack or flaw, it should burst in less than

one minute. Never start the tool with a person in line with the wheel. This includes the operator.

• In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel for cracks or flaws.

• NEVER have any part of your body in line with the path of the saw blade. Personal injury will occur.

• Clean your chop saw periodically following the procedure in this manual.

• Do not remove wheel guards or base.

• ALWAYS USE THE VISE OR SPECIAL FIXTURE TO CLAMP WORK SECURELY. Other aids such as spring, bar, or C-clamps may be appropriate for certain sizes and shapes of workpiece. Use care in selecting and placing these clamps and make a dry run before making a cut.

• Use only 14" type 1 wheels rated at 4100 rpm or higher.

• Allow cut off parts to cool before handling.

• Do not attempt to cut wood or plastic with this tool.

• NEVER CUT MAGNESIUM WITH THIS TOOL.

• Use chop saw in a well-ventilated area.

• Turn chop saw off before removing any pieces from the base.

• DO NOT CUT ELECTRICALLY LIVE MATERIAL.

• Do not use circular saw blades or any other toothed blades with this tool. Serious injury may result.

trabajo pesado D28715

Sparks or hot chips from cutting or arcing motor brushes may ignite combustible materials.

• Do not use the side of the abrasive wheel as a deburring grinder. This will substantially weaken the wheel creating an unsafe condition. The wheel may come apart.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other

construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or

lay on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disburse dust, which may cause

serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety

glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS wear certified safety equipment:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3)

• ANSI S12.6 (S3.19) hearing protection

• NIOSH/OSHA/MSHA respiratory protection.

CAUTION: Wear appropriate hearing protection during use. Under some conditions

and duration of use, noise from this product may contribute to hearing loss.

To Carry (Fig. 1)

Fold down unit to position where you can carry the saw. Push in lock pin (A) to lock arm down.

Unlocking (Fig. 1)

To unlock tool and raise head, depress motor arm slightly and pull lock pin (A) out. Motor arm will then pivot upward.

Material Clamping and Supporting

• Angles are best clamped and cut with both legs resting against base.

• A spacer block slightly narrower than the workpiece can be used to increase wheel

utilization (Fig. 3).

• Long workpieces must be supported by a block so it will be level with top of base

(Fig. 4). The cut-off end should be free to fall downward to avoid wheel binding.

Spark Deﬂ ector Adjustment (Fig. 1)

To best deflect sparks away from surrounding persons and materials, loosen the screw (B), adjust the spark deflector (C) and then retighten screw.

CAUTION: Risk of property damage. Do not allow cordset to come into contact with deflector or sparks as damage to cordset may occur.

Vise Operation (Fig. 5)

The vise has a quick travel feature. To release the vise (F) when it is clamped tightly, turn the crank (H) counterclockwise one or two times to remove clamping pressure. Lift the vise lever (I) up. Pull crank assembly out as far as desired. The vise may be shoved into work without cranking. Lower vise lever then tighten vise on work by using crank.

Fence Operation (Fig. 5)

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF

position. An accidental start-up can cause injury.

The fence (E) requires no tools to adjust. The quick-release clamp lever (T) unlocks and locks the fence. When the lever is rotated fully forward, the fence is unlocked. The fence can then be freely moved forward, backward or rotated to allow for the best cutting position for a new wheel and as the wheel wears.

Rotating the lever fully to the rear locks the fence in position selected. If the bottom leg of the lever is not horizontal (parallel to the base), the fence is not locked. Lever will only lock fence when there is strong resistance to moving it to rear. If resistance is light, adjust clamping force by tightening slightly the two bolts (R) holding the fence to the base. Test by reclamping and attempt to move fence.

Fence Angle Adjustment (Fig. 6)

position. An accidental start-up can cause injury.

The angle adjustment indicator is part of fence clamping system. Align the desired angle indicator line with the edge of the slot in base.

FOR A MORE ACCURATE SQUARE CUT

1. Unlock the fence.

2. Push the arm down until the wheel extends into the base.

3. Place a square against the wheel and adjust the fence against the square.

4. Lock the fence into position.

Usage (Fig. 1, 2)

Refer to Figure 2 for proper body positioning during use. To start the tool, depress the trigger switch (M). To turn the tool off, release the trigger

WARNING: Risk of personal injury. Check the work surface that the chop saw rests

on when replacing with a new abrasive wheel. It is possible that the wheel may contact ANY ITEMS OR STRUCTURE THAT EXTENDS ABOVE work surface (under the base) when the arm is fully lowered.

Mounting (Fig. 8, 9)

CAUTION: Tool must be supported on stable, level, non-skid surface to prevent

unexpected movement when operating.

PROCEDURE FOR PERMANENT MOUNTING

1. Drill four holes 5/16" (8 mm) through the work surface (Fig. 8).

2. Insert 1/4-20 screws down through the holes in the base and through holes in mounting surface. The approximate length of the screws should be the thickness of the mounting surface plus 4" (102 mm).

CRADLE MOUNTING

1. Cut two boards approximately 20" long x 2" high x 4" wide (508 x 50.8 x 101.6 mm).

2. Place chop saw at desired work location.

3. Place boards tightly along side, and nail to work surface (Fig. 9).

Operation Tips for More Accurate Cuts

• Allow the wheel to do the cutting. Excessive force will cause the wheel to glaze reducing cutting efficiency and/or to deflect causing inaccurate cuts.

• Properly adjust fence angle.

• Make sure material is laying flat across base.

• Properly clamp material to avoid movement and vibration.

MAINTENANCE

position. An accidental start-up can cause injury.

MOTOR BRUSH INSPECTION AND REPLACEMENT (FIG. 10)

Brushes should be regularly inspected for wear. To inspect brushes, unscrew the two end cap screws (W) and remove end cap (V). Remove brush cap (X). Brushes (Y) should slide freely in brush box. If brushes are worn down to .3" (8 mm) as shown in Figure 10 they should be replaced. To reinstall, push new brush back into brush box. If replacing existing brush, maintain same orientation as when removed. Replace the brush cap (do not overtighten). Replace end cap and two screws. Tighten securely.

Consignes de sécurité importantes

AVERTISSEMENT : lire et comprendre toutes les directives. Le non-respect des

directives indiquées ci-dessous peut entraîner des risques de choc électrique, d’incendie ou de blessures graves.

CONSERVER CES DIRECTIVES

• MAINTENIR LES DISPOSITIFS DE PROTECTION EN PLACE et en bon état de

fonctionnement.

• RETIRER LES CLES A MOLETTE ET LES CLES DE REGLAGE. S’habituer à vérifier

que les clés et les clés de réglage ont été retirées de l’outil avant de le mettre en marche.

• GARDER LA ZONE DE TRAVAIL PROPRE. Les zones et établis encombrés sont

souvent des causes de blessures.

• NE PAS UTILISER CET OUTIL DANS UN ENVIRONNEMENT DANGEREUX. Ne pas

utiliser d’outils électriques dans des endroits humides ou mouillés et ne pas les exposer à la pluie. Garder la zone de travail bien éclairée.

• TENIR LES ENFANTS A L’ECART. Tous les visiteurs doivent se trouver à une distance

sûre de la zone de travail.

• S’ASSURER QUE L’ATELIER NE PRESENTE PAS DE DANGER POUR LES ENFANTS en utilisant des cadenas, des interrupteurs principaux ou en retirant les clés de démarrage.

• NE PAS FORCER L’OUTIL. Le travail sera mieux accompli et plus sécuritaire au rythme prévu pour l’appareil.

• UTILISER L’OUTIL APPROPRIE. Ne pas forcer un outil ou un accessoire pour effectuer un travail auquel il n’a pas été conçu.

• UTILISER LA RALLONGE APPROPRIEE. S’assurer que la rallonge est en bon état. Lorsque qu’une rallonge électrique est utilisée, s’assurer d’en utiliser une de calibre suffisamment élevé pour assurer le transport du courant nécessaire au fonctionnement de l’appareil. Un cordon de calibre inférieur causera une chute de tension de ligne et donc une perte de puissance et une surchauffe. Le tableau suivant indique le calibre approprié à utiliser selon la longueur du cordon et l’intensité nominale de la plaque signalétique. En cas de doute, utiliser le calibre suivant le plus gros. Plus le numéro de calibre est petit, plus le cordon est lourd.

• PORTER LES VETEMENTS APPROPRIES. Ne porter ni vêtements amples, ni

gants, ni cravates, ni bagues, ni bracelets, ni autre bijoux, car ces derniers pourraient s’enchevêtrer dans des pièces mobiles. Le port de chaussures antidérapantes est recommandé. Se couvrir les cheveux s’ils sont longs. Se tenir éloigné des évents puisque ces derniers recouvrent souvent des pièces en mouvement.

• TOUJOURS PORTER DES LUNETTES DE SECURITE conforme aux exigences de la

norme ANSI Z87.1. Utiliser également un masque facial ou anti-poussière si l’opération de découpe génère de la poussière. Les lunettes courantes comportent seulement des lentilles résistantes aux chocs, ce ne sont pas des lunettes de sécurité.

• FIXER LA PIECE. Utiliser des brides ou un étau pour retenir la pièce. C’est plus

sécuritaire que d’utiliser votre main et cela vous permet d’utiliser les deux mains pour faire fonctionner l’outil.

• NE PAS TROP TENDRE LES BRAS. Conserver son équilibre en tout temps.

• PRENDRE SOIN DES OUTILS. S’assurer que vos outils sont aiguisés et propres

afin d’optimiser sécurité et performance. Suivre les consignes de graissage et de changement d’accessoires.

• DEBRANCHER LES OUTILS avant de les réparer et au moment de changer

d’accessoires, tels que les lames, les mèches, les couteaux, etc.

• REDUIRE LE RISQUE DE DEMARRAGE ACCIDENTEL. S’assurer que l’interrupteur

est en position ARRÊT avant de brancher l’outil.

• UTILISATION DES ACCESSOIRES RECOMMANDES. Une liste des accessoires

recommandés se trouve dans le mode d’emploi. L’utilisation d’accessoires incorrects peut entraîner un risque de blessure corporelle.

• NE JAMAIS SE TENIR SUR L’OUTIL. Une blessure grave pourrait se produire en cas

de basculement de l’outil ou de démarrage accidentel de l’outil de découpe.

• VERIFIER LES PIECES ENDOMMAGEES. Avant toute utilisation ultérieure de l’outil,

un protège-lame (ou une autre pièce) endommagé doit être soigneusement examiné afin de déterminer s’il fonctionnera correctement et remplira sa fonction prévue – vérifier l’alignement des pièces mobiles, la présence de grippage des pièces mobiles, de rupture de pièces, la fixation et tout problème pouvant nuire au fonctionnement de l’outil. Un protège-lame (ou tout autre pièce) endommagé doit être réparé et remplacé adéquatement.

• NE JAMAIS LAISSER L’OUTIL FONCTIONNER SANS SURVEILLANCE. ETEINDRE L’APPAREIL. Ne pas laisser l’outil tant qu’il n’est pas complètement arrêté.

• PIECES DE RECHANGE IDENTIQUES. Pour la réparation, utiliser uniquement des pièces de rechange identiques.

• POUR REDUIRE LE RISQUE DE CHOCS ELECTRIQUES :

a. Cet équipement peut être pourvu d’une fiche polarisée (une broche est plus large

que l’autre.) Cette fiche pourra être insérée dans une prise polarisée, dans un sens seulement. Si elle ne s’insère pas dans la prise, demander à un électricien compétent d’installer une fiche polarisée.

b. L’outil peut comprendre une fiche de mise à la terre à trois broches. Cette fiche ne

doit être insérée que dans une prise mise à la terre. Si elle ne s’insère pas dans la prise, demander à un électricien compétent d’installer une fiche polarisée.

c. Ne modifier la fiche en aucune façon.

Autres règles de sécurité pour la scie fendeuse

• Toujours porter une protection oculaire et respiratoire adéquate.

• Avant d’utiliser l’outil, inspecter la meule de coupe à la recherche de fissures ou de défectuosités. Si une fissure ou une défectuosité est présente, jeter la meule. La meule doit également être inspectée lorsqu’il est possible que l’outil soit tombé. Les défectuosités peuvent causer un bris de la meule.

• Au moment de démarrer l’outil avec une meule neuve ou de rechange, ou en cas d’incertitude quant à l’état de la meule, tenir l’outil dans un endroit bien protégé et le laisser fonctionner pendant une minute. Si la meule comporte une fissure ou

une fêlure non détectée, l’accessoire devrait éclater en moins d’une minute. Ne jamais démarrer l’outil lorsque quelqu’un est aligné avec la meule. Cela inclut l’opérateur.

• Durant le fonctionnement de l’outil, éviter de faire rebondir le disque ou de le traiter rudement. Dans ces cas, arrêter l’outil et inspecter la meule pour toute trace de fissure ou de fêlures.

• AUCUNE partie du corps ne doit se trouver dans la trajectoire de la lame de la scie. Il y a risque de blessures corporelles.

• Nettoyer périodiquement la scie fendeuse selon la procédure indiquée dans le présent manuel.

• Ne pas enlever le protège-meule ni la base.

• TOUJOURS UTILISER L’ETAU OU LE DISPOSITIF DE FIXATION SPECIAL POUR BIEN SERRER LA PIECE. D’autres accessoires tels que des pinces à ressort, des serres à barre ou du serre-joint en C peuvent convenir à certaines tailles et formes de pièces. Choisir et placer judicieusement ces accessoires, puis faire fonctionner l’outil à sec avant de réaliser une coupe.

• Utiliser uniquement des meules de 533 mm (14 po) type 1 dont la vitesse atteint au moins 4100 tr/min.

• Laisser les pièces coupées refroidir avant de les manipuler.

• Ne pas tenter de couper du bois ou du plastique avec cet outil.

• NE JAMAIS COUPER DU MAGNESIUM AVEC CET OUTIL.

• Utiliser la scie fendeuse dans un endroit bien ventilé.

• Éteindre la scie fendeuse avant d’enlever tout morceau de la base.

• NE PAS COUPER DE MATERIAU SOUS TENSION.

• Ne jamais utiliser de lames de scie circulaire ou toutes autres lames dentées avec l’outil. Elles pourraient provoquer de graves blessures.

• NE PAS FAIRE FONCTIONNER CET OUTIL PRES DE LIQUIDES INFLAMMABLES, DE GAZ OU DE POUSSIERE. Les étincelles ou copeaux chauds, qui proviennent

de la coupe ou des balais du moteur émettant des décharges électriques, peuvent enflammer du matériel combustible.

• Ne pas utiliser le côté de la meule abrasive comme machine à ébavurer. Cela risque de fragiliser considérablement la meule et de créer une condition dangereuse. La meule risque de se séparer.

AVERTISSEMENT : certaines poussières produites par les activités de ponçage, de

sciage, de meulage, de perçage ainsi que d’autres activités de construction peuvent contenir des produits chimiques pouvant causer le cancer, des anomalies congénitales ou d’autres problèmes liés aux fonctions reproductrices. Voici quelques exemples de ces produits chimiques :

• le plomb contenu dans les peintures à base de plomb,

• la silice cristalline de la brique, du ciment et d’autres produits de maçonnerie, et

• l’arsenic et chrome provenant de bois traité chimiquement.
